Diffusion Combustion of a System of Plane Supersonic Hydrogen Jets in a Supersonic Flow

摘要

Calculation results for diffusion combustion of a system of plane supersonic hydrogen jets in a supersonic flow are presented. The calculations are based on parabolized Navier-Stokes equations closed by the one-parameter (K-L_omega) model of turbulence and a multistage mechanism of hydrogen oxidation. The influence of the air-flow composition and fuel-injection methods on the shape of the flame front and combustion effciency of hydrogen is analyzed.
