This invention discloses a porous rectifying structure for the afterburner of a variable cycle engine, comprising a rectifying orifice plate installed in an annular channel between the turbine outlet and the flame stabilizer. The orifice plate is symmetrically arranged along its radial central axis, with the clogging area facing the turbine inflow and axially aligned with the heat shield inlet. The orifice plate height is 2 / 3 of the channel height between the central cone and the heat shield. The plate has uniformly distributed pores with an equivalent diameter of 10-20 mm along the radial direction, with a clogging ratio of 5%-25%. This invention forms a multi-stage mixing interface through the radially gradient porosity pore arrangement, promoting shear mixing of the high-temperature internal combustion gas and the external bypass gas. Simultaneously, the static pressure difference across the orifice plate drives the external bypass gas flow into the heat shield cooling channel, increasing the cooling flow rate, improving the uniformity of the upstream velocity field of the flame stabilizer, eliminating the recirculation zone inside the heat shield, reducing the thermal load on the casing wall, and controlling the total pressure loss to within 3%, achieving high-stability combustion and reliable thermal protection under a wide bypass ratio.

The application discloses a high-efficiency carbon fixation microalgae breeding device, and relates to the technical field of carbon fixation microalgae breeding.The device comprises an elongated pool, a partition plate is arranged at the middle position of the elongated pool, so that a loop-shaped channel in the shape of a long strip is formed in the elongated pool, bottom plates are arranged in the two parallel straight channels of the loop-shaped channel, the upper surfaces of the bottom plates are arranged in an inclined manner, and the inclined directions of the two bottom plates are opposite.Two liquid lifting mechanisms are arranged at the high end positions of the two bottom plates respectively, and are used for lifting the algal liquid in the loop-shaped channel to the high end of the bottom plate, so that the algal liquid flows downward along the upper surface of the bottom plate automatically.Two groups of disturbance mechanisms are arranged on the upper surfaces of the two bottom plates.The algal liquid is driven to form a turbulent state by the bidirectional inclined bottom plates, the liquid lifting mechanism and the disturbance mechanism, the problems of surface light inhibition and bottom dark area are reduced, and the light energy utilization efficiency of the microalgae is improved significantly.

This invention relates to the field of water-saving and fertilizer-retaining technology for fruit trees, and discloses a water-saving, fertilizer-retaining, and frost-resistant cultivation device for fruit trees. The device includes a pipe buried 80-120cm apart at a depth of 50cm in the planting row spacing of the fruit trees. The outer surface of the pipe has several absorption holes for draining water and fertilizer from the pipe. The top of the pipe is covered with a layer of sand and gravel and kraft paper to cover the absorption holes. This water-saving, fertilizer-retaining, and frost-resistant cultivation device and its method of use, by burying the nutrient trough precisely where most of the fruit tree's root system is located, only requires a small amount of water and fertilizer or nutrient solution to be injected. This avoids the large amount of fertilizer that accumulates in the soil and is not well absorbed and utilized by the roots, resulting in fertilizer waste and soil pollution, which is a consequence of trenching and spraying fertilization. It also saves water wasted on surface irrigation, achieving a good water-saving and fertilizer-retaining effect, and effectively prevents the serious impact of early spring frost on fruit tree flowering.
