Abstract: Drag reduction by Energy Deposition (ED) as an energy-saving and efficient flow control technology exhibits outstanding performance in the field of supersonic vehicles, and in particular, hypersonic vehicles. With advantages such as quick response, high energy utilization, strong reliability, stable parts, and remote manipulation, energy deposition has a broad application prospect. This paper focuses on the mechanism of and current theoretical research on energy deposition, presenting the classical flow field phenomena such as the lensing effect, the vortex ring, and the air cone. The process of drag reduction by energy deposition and the mechanism of the flow field structure are discussed, and the key factors affecting the drag reduction effect by energy deposition are analyzed. By summarizing the development status of energy deposition generators, this paper expounds the possibility of practical application of energy deposition drag reduction, and prospects the future research on energy deposition drag reduction and other types of flow control using the energy deposition principle in China.
