Abstract

The numerical simulation has been carried out to investigate the cold flow characteristics for mixing efficiency and flame stability of the composite structure of pylon and cavity in the supersonic combustion. The different combination distance of pylon /cavity structure has been comparative analyzed and investigated. It is noted that the pylon can increase the penetration depth of the jet and mixing efficiency, and it won't lead to a higher total pressure loss. The decrease of combination distance enhances the blending and improves the flame stability, but also increase the total pressure loss. Moreover, the distance between pylon and injector of 6d is recommended regarding high mixing efficiency and less total pressure loss.

Key words： supersonic combustion; pylon; cavity; numerical simulation
