| Abstract: | The mixing and combustion of hydrocarbon(methane) in supersonic flow were investigated numerically by using Reynolds average equations. The turbulent model of Baldwin Lomax algebraic eddy viscosity and the chemical models of implicit treatment of chemical source term were adopted. Numerical results were analysed and compared with one of hydrogen fuel.The results show that the chemical model established is reasonable and the numerical method is reliable. The hydrocarbon fuel is a prospective fuel in supersonic combustion flow. |
