Equivalent thermodynamic system for spray-cooler in active ejection altitude simulation facility

水喷雾冷却器在主动引射高空模拟试车台中具有重要作用,其出口处温度的有效控制是保障试车正常运行的关键。针对某型号火箭发动机常压试验的喷雾冷却器,建立了等效热力系统模型,并在Simulink平台上建立了相应的动态仿真模型,计算结果与试车测试结果对比证明所建等效热力系统模型正确,从而为实现其出口处温度的有效控制提供依据。

The key role of spray-cooler for hot gas in active ejection altitude simulation facility, indicates that the control of temperature of hot gas ensures regular service for tests. The equivalent thermodynamic system is modeled for the spray-cooler which have been tested under atmosphere. Simulation is done on the basis of Simulink. The result shows the correctness of the model by compared with the experimental date. It can provide the method to control temperature of exhaust gas.
