  • For generating uniform air flow at Laval nozzle outlet,the influences of the form,velocity ratio and pressure drop of the injection was studied.An air heater with two forms of injection and a Laval nozzle were designed,then FLUENT was used to simulate the combustion and flow filed.The result show that:there is little influence from the form of the injection,which mainly influences the temperature of the injector;the lower velocity rate and oxygen drop of the jet means the more uniform of nozzle outlet and approximative contraction ratio in two directions is better for the outlet.
