Abstract

Abstract

This paper gives a new method of solution to fluid field in the DF chemical laser combustion chamber. The method is a numerical solution of multi-component chemical equilibrium flows with the elements distributing equations and thermodynamic calculation of chemical equilibrium. This method avoids the problem of stiff equations caused by chemical reaction source terms in the components equations, and the number of components equations is reduced. The result shows that the wall of the combustion chamber is cooled down to a certain extent by the gas helium injected.
