This invention discloses a concave cavity flame stabilizer structure, its fuel injection and cooling method, and an afterburner. The structure includes a symmetrical Tesla valve, a fluid oscillator, and shape memory alloy ribs. The Tesla valve is located at the front end of the evaporation chamber of the afterburner, utilizing its unidirectional flow resistance characteristics to suppress fuel backflow caused by pressure fluctuations and ensure stable fuel supply. The fluid oscillator replaces the traditional injection hole, converting the fuel-air mixture into a high-frequency, large-scale periodic swept jet injected into the concave cavity, improving atomization, evaporation, and mixing efficiency. The shape memory alloy ribs are located on the cold side of the bottom and rear wall of the concave cavity, automatically adjusting their shape according to changes in wall temperature to achieve dynamic matching between cooling intensity and heat load. This invention, through the system integration of fuel supply, combustion, and cooling, solves the problems of fuel backflow, low atomization efficiency, and poor adaptability of the cooling system under wide operating conditions in traditional concave cavity structures, significantly improving the combustion efficiency and thermal protection reliability of the afterburner.
