Under hypersonic flight conditions， the residence time of fuel in the scramjet combustor is extremely short， while sufficient mixing， ignition， and stable combustion of fuel and oxidants are important issues for hypersonic propulsion. To improve the mixing and combustion performance of fuel in the combustion chamber， domestic and foreign researchers have introduced mixing and combustion stabilization devices such as struts， ramps， cavities， and backward steps into the combustor， and have obtained certain achievements. In previous studies， the recirculating zone formed by the strut and cavity in the flow field can achieve good mixing and combustion stabilization performance， receiving widespread attention and expansion. This paper reviews the recent research progress on strut， cavity， and strut-cavity combination configurations around the world， and explores the future development direction of related research.
