摘要：
The results of numerical and experimental investigations of hydrogen mixing and ignition processes in a supersonic combustion chamber with backward facing steps located on the channel walls are presented. The study is focused on the investigation of ignition conditions and flow structure in the combustor taking into an account hydrogen multi jet injection. 3D numerical simulations were conducted by means of ANSYS FLUENT 18.0 on the BANS-based approach. The experiments were carried out at the hotshot with tunnel IT-302M. The satisfactory agreement between experimental and numerical data by static pressure distributions on a channel walls was received. The flow structure was analyzed in details and the influence of free stream Mach number and the jet injection angle were shown. The results can he used for optimization of supersonic combustor chamber parameters and choosing injection schemes.
