| Abstract: | A combustor with a shear tricoaxial gas-gas injector was researched numerically and experimentally.The influence of propellants temperature in the injector inlet on the combustion performance and wall temperature was investigated and analyzed.The numerical simulation results show that the variable momentum ratio of fuel to oxidizer which brought by the variable propellants temperature is the main factor.The influence of the fuel temperature on the combustion performance and wall temperature is more obviousl... |
