Paper Title:
Flow Field Characteristics of Butterfly-Type Cavity and its Influence on Supersonic Flow
  Abstract

A new type of cavity configuration — butterfly-type cavity applied in the scramjet is proposed in this paper. The supersonic combustion chamber with Butterfly-type cavity was investigated numerically and experimentally. Results show that the horizontal vortex moving along the Y direction is helpful in gathering hydrogen gas, but the vertical vortex moving along the Z direction is not. Both turbulent kinetic energy and turbulent kinetic energy dissipation rate are very high at the junction between the cavity and the main combustion chamber. And the production of turbulent kinetic energy is agreeable with that of turbulent kinetic energy dissipation.
