The Numerical Simulation Of The Combustor Of Scramjet

Global one-dimensional finite volume Euler equations coupled with chemical reactions are implicitly solved to simulate the reacting flowfield of the combustor of Scramjet fueled by hydrogen or hydrocarbon. The convective term is solved by AUSM+(a sequel to AUSM which means "the advection upstream splitting method"). The 7 species 8 steps model and 7 species 7 steps model of Hydrogen/Air is used in the hydrogen reacting flowfield, The 9 species 5 steps model of methane, the 10 species 10 steps model of ethane and the 10 species 13 steps model of kerosene are used in the hydrocarbon reacting flowfield, the results of the distributions of velocity, Mach number, pressure, static temperature, total temperature, species mass fraction and the combustion efficiency are gained, and the numerical results of the pressure of hydrogen and methane are compared with those of the experiment.
