Description

Title of the invention: Gas engine cycle using a TESLA valve Technical field of the invention

[0001] A new Tesla valve geometry, [Fig.1], increases the efficiency of the gas engine cycles [Fig.9]-[Fig.10], preferentially aerodynamic, making them relevant for applications of solar thermal, wind kinetic, geothermal, and waste heat energy capture, opening the way to synergistic mixed solar, wind, and thermal pure captures. Technological background

[0002] The principle of a Fig-2 STTC (Solar Thermal Cyclonic Turbine) developed by the company NST (N. Ugolin 2016), a variant of a thermal tower also called an aerothermal power plant or solar chimney, allows the conversion of solar thermal energy into kinetic energy.

[0003] Unlike wind turbines which exploit the translational energy of the wind, the operation of thermal chimneys relies on convective air movements from bottom to top, generated by a temperature gradient.

[0004] Thus, a solar thermal chimney is a type of miniaturized thermal chimney operating on the basis of an aerodynamic cycle powered by solar energy, capable of generating a powerful convective flow followed by a shear of said flow resulting from a forced fall. The bidirectional kinetic energy of the flow is recovered through a rotor comprising two sets of inverted blades to produce mechanical work.

[0005] A classic STTC [Fig.2] consists of a tube 6 to 12 m high, with a diameter not exceeding 400 mm, allowing urban use, included in the infrastructure of buildings, as street furniture or in a classic industrial installation.

[0006] The operation is based on a thermal pumping of air using solar thermal energy 13 deposited in a high position on a radiator 6. This energy thus generates a significant acceleration of the flow, capable of setting in motion a particular double-flow wheel or rotor comprising two sets of reversed blades 7. The radiation and convection energy is obtained for example by heating the radiator 6 with radiation from a solar concentrator, a laser or any other thermal source.

[0007] The rising air circulating in an external chamber 9 passes through a first set of rotor blades 7, the rotation of the rotor driving a fixed shaft.

[0008] At the rotor outlet, the heated air enters a cyclone 11, with a longitudinal inlet, through a set of fixed vanes 12, thus imparting a circular motion to the rising air, so as to form an upward vortex in the cyclone.

[0009] The apex of the conical cyclone forces the backflow of air to form a downward flow. The downward flow then passes through the second set of inverted blades of the rotor 7 of the twin-flow turbine, further accentuating the rotation of the shaft.

[0010] The vortex tube type heat exchange effect is obtained in part by the shearing of the rising and falling gas flows in the cyclone.

[0011] Different technological building blocks are assembled to construct a standard model of a STTC.

[0012] [Fig.3].

[0013] In particular two critical parts which are a radiator in a high position transferring thermal energy to the gas flow circulating in the STTC;

[0014] [Fig.4]-6

[0015] and a divergent whose role is to regulate the downward flow in order to amplify the suction effect resulting from the contraction of the flow cooled on the descent.

[0016] [Fig.4]-10

[0017] With the retained radiator geometry, the gas velocity exhibits a linear dependence on the radiator equilibrium temperature with a slope of -0.05 and a correlation coefficient R of 0.995 between 393.2 K and 793.2 K.

[0018] [Fig.5]

[0019] Beyond 793.2 K we observe a loss of transfer efficiency, whereas below 393.2 K, the efficiency is maximal.

[0020] The loss of efficiency at high temperatures results from a decrease in the conductivity performance of the material composing the radiator, concomitant with a degradation of the material.

[0021] The kinetic power of the gas as a function of the energy deposited in the gas

[0022] Fig-6

[0023] shows a relatively low transfer rate.

[0025] Velocities, pressures and temperatures of the gas flows rising and falling downstream of the radiator 6 at each temperature of the latter.

[0026] For example, considering only three capture points on the STTC such as: • a point at the rise with an optimum calculated capture coefficient (Cp), between 54 and 55% for the external blades of the double-flow impeller, and • two additional capture points, corresponding to the descent • on the one hand, to the internal part of the double-flow impeller 7, inverted blades and • on the other hand, to another simple wheel with inverted blades, attached to the axle at its lower part, • the internal part of the double-flow wheel and the second wheel each having an optimum calculated capture coefficient between 33 and 40%,

[0027] It follows that the cumulative efficiency of mechanical energy extraction is between 5.4% and 2.11% of the thermal energy deposited.

[0029] Power recovered at each radiator temperature

[0030] This efficiency can increase cumulatively with the addition of additional capture stages, i.e. by introducing more wheels along the axis of rotation.

[0031] These yields, although modest, remain superior to those obtained for most solar chimneys.

[0032] However, in order to be complementary to other renewable energy technologies, particularly to the two major ubiquitous renewable energy capture technologies of photovoltaics and wind power, these efficiency values ​​must be improved.

[0033] To achieve this, two main technological barriers can be considered: • the rate of transfer of energy deposited on the radiator into internal energy over the widest possible range of energy power deposited on the radiator • the rate of internal energy transfer into kinetic energy Summary of the invention

[0034] The object of this invention is to provide a solution to improve these two points:

[0035] In addition, it appears that the method of extracting kinetic energy from a gas by turbine as carried out by STTC offers extraction efficiencies of between 33 and 55%, higher than the efficiencies of other methods of extracting kinetic energy by giant propeller wind turbine whose efficiencies are between 20 and 50%.

[0036] Beyond improving the limitations of STTC for capturing thermal energy, this invention proposes a new geometry for capturing translational kinetic energy using STTC to increase capture efficiencies and reduce the size of devices compared to wind-powered devices of the same power.

[0037] The innovation presented in this document makes it possible to further improve the efficiency of the number of Gas Engine cycles by coupling all or part of the invention to existing or conceivable Gas Engine cycles for future applications.

[0038] The present invention thus relates to a method for an open or closed motor cycle, using at least one gas as a driving force to power an effector such as: - a wheel, - a turbine, - a cylinder, - a pneumatic motor, and more generally an effector using a gas flow to produce mechanical motion, characterized in that the motor cycle circuit comprises at least one Tesla valve such that at least one Tesla valve comprises, in the x,y plane, a main conduit, with a width between 500p and 5cm, onto which are grafted, in the same x,y plane, loop conduits with a width between 500p and 5cm, said loops being offset from each other, by so that in the direction passing A to B, the flows in the main channel and in the loops are confluent in a Y shape allowing a turbulence-free flow through the valve, whereas in the blocking direction, B to A, the flow in the loops and the main channel are confluent in an X shape, forming disturbances and turbulence which slow down the flow in the TES LA valve, until it blocks the flow at the outlet, so that the motor cycle only works in the direction passing A to B of the TESLA valve.

[0073] [Fig.21] Detailed description of the invention

[0074] 1. The invention is based on Tesla valve technology such as:

[0075] patented by Nikola Tesla in 1920, the so-called Tesla valve, has the advantage of allowing circulation fluids in one direction A to B while strongly penalizing the opposite direction of circulation B to A.

[0076] No mechanical device is required for the operation of the Tesla valve, since the automation is based solely on the ingenious exploitation of fluidic phenomena.

[0077] [Fig.7]

[0078] The tests, carried out with a Tesla valve of conventional geometry (VTC), such that the VTC valve comprises a main conduit 17, between 500p and 5cm wide in the x,y plane, and such that loop conduits between 500p and 5cm wide in the x,y plane are grafted onto said main channel, the loop conduits 18 being offset from each other such that: • in the direction passing from A to B, the flows in the main channel x and the loops are confluent in the shape of y 19, • whereas in the directions blocking B towards A the flows in the loops and the main channel are confluent in an X-shaped pattern (20°).

[0079] confirm a laminar flow in the direction passing A to B without significant acceleration of the outlet fluid.

[0080] [Fig.7], A to B.

[0081] Whereas in the blocking direction B towards A the flow is greatly slowed in the main channel by the appearance of turbulence at the X 20 junctions,

[0082] [Fig.7], B to A.

[0083] Thus, strong accelerations in the loops shear the flow of the main channel, disturbing the flow rate of the main channel by reducing its output.

[0084] Unfortunately, in the tested speed regimes between 3 and 35 ms 1 of injection flow in the direction A to B or B to A, only the very high injection speeds beyond 25 ms *, allow us to observe a VTC operating regime for which the flow in the direction A to B is significantly greater than the flow in the direction B to A.

[0085] [Fig.8]

[0086] These high flux speeds therefore represent the regime from which it might be possible to consider integrating VTC into an engine cycle using a gas as the mechanical fluid for: • either improve the efficiency of the engine cycle by increasing the volumetric flow rate at the VTC outlet, through an increase in flow velocity, • either a regulation of the handling of incident fluids arriving via different routes and exhibiting at least one of the following different parameters such as: • pressure, • speed, • temperature

[0087] so that flows with different parameters can drive together, without backflow between arrival paths, the same effector, such as turbine, wheel, motors or any other effectors producing a mechanical movement from the kinetic energy of a gas flow.

[0088] Let a combination of the two preceding functions.

[0089] [Fig.9], [Fig. 10],

[0090] To increase the performance of a VTC and adapt it to gas engine cycle applications over a wide range of inlet flow velocities between 3 ms⁻¹ and 35 ms⁻¹ injection, we designed a new longitudinally asymmetric Tesla valve by introducing a variation in the geometry of the loops in region "A" in Fig. 1, called stop loops [Fig. 1]-3. The stop loops include at least one couple of loops called pseudo-symmetric loops 3, that is to say symmetric with respect to the main channel and translated with respect to each other by an amount less than 3 times the width h 4 of the lumen of the duct of the pseudo-symmetric loops.

[0091] Preferably, the stop loops comprise 3 pairs of pseudosymmetric loops at the beginning of the valve in position A.

[0092] We call this valve T2PS for Tesla Valve Pseudo-Symmetric Termination.

[0093] [Fig. 1]

[0094] The new geometry, T2PS, tested under the same conditions as the VTC in the direction A to B and the direction B to A,

[0095] [Fig. 11]

[0096] exhibits a flow rate difference of a factor greater than or equal to 1.2 for the entire injection velocity range studied between 3 and 35 m / s.

[0097] [Fig. 12]

[0098] This factor greater than 1.2 between the outlet velocities passing from A to B and blocking B to A is observed, for the same injection velocity in the range 3 and 35 m / s, for all types of gas tested, including: • dry air • humid air (between 70 and 100%) • nitrogen, • argon, • oxygen, • helium, • hydrogen, • water vapor, • CO2 • a mixture of these gases mentioned.

[0099] By extension, the T2PS valve will exhibit the same properties for ideal gases, Newtonian gases and most real gases or gas mixtures. 1. In a particular embodiment, the conduit of the main channel and the

[0100] loops of the T2PS valve are stretched along the same direction z Fig-1 perpendicular to the y and x plane, the plane in which the loops and the main channel are inscribed, so as to form valves enlarged in the z direction, but retaining their initial dimensions in the x,y direction plane in which the loops and the main channel are inscribed.

[0101] [Fig.l3]-26

[0102] Several stretched T2PS valves can be stacked to form a stacked valve front [Fig. 13]-27 such that the T2PS valves of the valve front are parallel to each other in the x,y plane where the loops and the main channel of each valve are inscribed, said plane forming a single plane for all the valves. 1. In a particular embodiment, the stretching along the z direction can take any form, in particular circular or trapezoidal in a 28 grand piano shape, so as to obtain valves of the shape of the stretching in the z direction, in particular a circular shape, trapezoidal shape, or any other shape allowing them to be integrated into the elements of a motor circuit, while the T2PS valve retains its initial dimensions h in the (x,y) plane in which the loops and the main channel are inscribed. 2. In a particular embodiment, the stretching in the (y,z) plane [Fig. 14] is achieved by circular convolution around x, by elongating the valve in a circular shape in the (y,z) dimension. The T2PS retains its initial dimensions in the yz dimensions with respect to x, from which it remains equidistant, through successive convolutions in the y,z dimension where the loops and the main channel are inscribed. The T2PS valve then forms a cylinder.

[0103] For the production of a cylindrical valve, it is possible to decompose the different portions of the valve into sections, parts, or quarters [Fig.14]-30, like a slice of cake,

[0104] The elements of the T2PS valve are held in place by a plane 31 in the x direction forming one of the faces of the part. The cylinder is reconstituted by juxtaposing the parts 32. 1. In a particular embodiment, T2PS valves or valve fronts [Fig.15]-27 are arranged at the tangential inlets 35 of a cyclone or tube, allowing a translational flow such as wind to be captured by the tangential inlets 35 equipped with collection cones 36 to convert it by accelerating it into a vortex Fig-16 which can be exploited by the arrangement of impellers equipped with blades attached to a central axis at the center of the cyclone or tube. 2. The T2PS valves arranged regularly with capture cones at the tangential inlets according to for example [Fig.l7]-37-38 a central symmetry or a revolution around the cyclone or tube allow to redirect inside the cyclone or tube a translational flow, whatever its direction, to form a descending vortex with an acceleration of the flow speed while avoiding reflux or leakage [Fig.l7]-39 from one tangential inlet to another even for the unexposed inlets.

[0105] Any symmetry or revolution can be exploited [Fig.17]-40

[0106] It is always possible to use tangential inlet and single capture cone systems without T2PS valve, provided that said inlet is orientable by rotation of all or part of the cyclone or tube according to the direction of the wind.

[0107] To this latter geometry, systems with two collection cones directed in the same direction and orientable by rotation of all or part of the cyclone or tube will be preferred. Said collection cones will be equipped with T2PS valves or valve faces, and one of the collection cones will have a flow direction reversal so that the flows from both cones are injected in the same direction of rotation at the tangential inlets, thus doubling the collection area and improving efficiency without backflow or leakage.

[0108] The system of the invention will, for example, be an angled conduit disposed upstream of the tangential inlet of one of the cones, allowing the direction of the flow of the latter to be reversed 1. In a preferred embodiment, an STTC turbine Fig-18-41 is disposed at the center of a cyclone [Fig. 18]-34 comprising at least one tangential inlet associated with one of the collection cones equipped with a T2PS valve.

[0109] The vortex formed by capturing the tangential flow to the cyclone is then converted into a central flow rising to the center of the cyclone, thanks to the cone of the cyclone.

[0110] Said upward central flow then enters the outer tube of the STTC to be exploited in the same way as a flow entering at the foot of the STTC, possibly undergoing all the thermal treatments and accelerations encountered in the implementation of the STTC and being exploited to produce work through the wheel system of the STTC.

[0111] This geometry allows simultaneously or sequentially the exploitation, using a gas or an aerodynamic fluid, of wind energy and solar thermal energy, with a single system, forming a mixed synergistic solar wind turbine. 1. In a particular embodiment a cylindrical T2PS valve [Fig.l9]-43 is disposed in the outer tube of the STTC, so as to channel and accelerate the flow reflected by the lower cone of the cyclone, such that the loss of kinetic energy of the flow resulting from the reflection by the cyclone cone is redirected into an upward central flow, either partially or totally compensated.

[0112] [Fig.21]-B 1. In this embodiment, an air / air or water / air heat exchanger is located at the level of the external wall of the T2SP.

[0113] [Fig.l9]-44

[0114] In order to effect a heat exchange between the flow passing through the T2PS and the exchanger, allowing heat to be supplied to the T2PS which will be transferred to the flow circulating in the T2SP. The heat can be of any origin: fatal, nuclear, geothermal, solar geothermal.

[0115] This Heat will be transformed into kinetic energy in the flow by the T2PS.

[0116] Indeed, by replacing the standard STTC radiator with a T2PS cylindrical one.

[0117] [Fig.l9]-45

[0118] it appears that the conversion efficiencies of thermal energy into kinetic energy and pressure as well as the transfer of thermal energy to the flow are improved compared to conventional radiators.

[0119] [Fig.20]

[0120] This efficiency allows larger quantities of energy to be transferred without the construction material of the radiator melting. 1. In a mixed containment mode where the speed of the flow entering TTCP increases by wind capture for example with an STTC equipped with T2SP which receives energy;

[0121] [Fig.21]-A

[0122] it appears that the velocity of the flow increases exponentially as a function of the thermal energy supplied to the radiator and the velocity of the flow. CAPTIONS FOR ALL FIGURES
