Numerical Simulation of the Flow in the Scramjet Combustion Chamber Taking into Account Nonequilibrium Chemical Reactions

Resumo

A method for numerical simulation of the combustion of hydrogen in a supersonic air flow is developed. Comparison of the calculation results with the experimental data showed a satisfactory agreement. The calculation results using the nonequilibrium and equilibrium techniques differ from each other. It is shown that combustion parameters substantially depend on the geometric characteristics of the inlet device, the combustion chamber and the nozzle.
