Numerical Simulation of Solid Fuel Ramjet Combustion Chamber Under Different Air Fuel Ratio

Numerical investigation of the complex turbulent flow and chemical reaction in solid rocket ramjet under different air-fuel ratios was carried out. Multicomponent compressible gas with chemical reaction equation is established. Make the fluid-heat coupling code with the finite volume method, based on numerical format, implicit time discrete, add the PDF model. The results show that the numerical method exhibits the better agreement with the experimental measurements. In general, the proposed numerical procedure applied in the present paper shows good capability in predicting the physical phenomena and the flow characteristics encountered in such kinds of complex turbulent flow.
