Embodiment Construction

[0027] Achieving standing detonation waves in experimental engines can be challenging, but using computational models can significantly increase the likelihood of success. For example, through an iterative approach, computational modeling can enable researchers to determine effective geometries and boundary conditions without building a series of prototypes. The computational model should take into account conservation laws, chemical reaction mechanisms, and stability considerations. The detonation wave can be modeled as a shock wave following the reaction zone. To simplify calculations and reduce calculation time, the detonation wave can be modeled as an ideal fluid with no change in gas molecular weight. The energy increase can be assumed to occur in a single-step chemical reaction. To further simplify the calculations, the effects of heat conduction and viscosity can be neglected. The two-dimensional reaction Euler equations of the resulting system can be efficiently sol...

Abstract

A detonation engine (100) capable of detonating a mixture of fuel and oxidant in a cylindrical detonation region (205) to perform work. The detonation motor may have first and second inlets (135, 140) having ends fluidly connected from the tank to the detonation motor. The first and second inlets may be aligned along a common axis (145). The inlets may be connected to nozzles (105, 110) and separators (115) may be placed between the nozzles and along a common axis.

Description

[0001] priority claim [0002] This application claims priority to US Provisional Application Serial No. 61 / 712,972, filed October 12, 2012, which is incorporated by reference in its entirety. technical field [0003] The present invention relates to a detonation standing wave engine (standing detonation wave engine). Background technique [0004] Gas-phase detonation waves can propagate in and be affected by various geometries. In cylindrical rigid tubes, the propagation can be in the form of multi-cellular detonation in large diameter tubes, rotational detonation in medium diameter tubes, and / or in very small diameter tubes There may be galloping detonation in the tube. Similar cellular or galloping modes can also be achieved in rectangular cross-sectional channels of various aspect ratios. Between parallel plates, when the gap between the plates is much smaller than the transverse span of the plates, two-dimensional cellular detonation can be achieved because the shear...
