Mixing and combustion in supersonic combustor with flame holders
Numerical investigation was conducted to understand the dynamic mechanism and effect of shear layer on the mixing and combustion of supersonic flow in a supersonic combustor with cavities.The complex wave structure including shock wave,expansion wave and the interaction of shock wave with shear layer could effectively and significantly increase mixing; and the mass and momentum exchanges between backflow zones in the cavities and main flow would enhance the ignition and stabilization of combustion.
