Abstract:
In order to meet the requirement of liquid oxygen filling temperature in the test of a launch vehicle power system, the thermal performance in the filling process is analyzed. The temperature rise caused by heat leakage and flow resistance loss in normal liquid oxygen filling process, and the temperature rise caused by efficiency loss of liquid oxygen pump are calculated theoretically to get the temperature variation regularity in normal liquid oxygen filling process. The thermal performance of super cooling liquid oxygen filling process was obtained by theoretical calculation and numerical simulation of super cooling temperature mixing characteristics. The above analysis result and the detected result are contrasted. The results are coincided with experimental data. The results show that the thermal characteristic analysis method for liquid oxygen filling process is correct and feasible.
