CFD를 이용한 로켓 공력가열 온도 예측

AERODYNAMIC HEATING TEMPERATURE OF SOUNDING ROCKET USING CFD

Aerodynamic heating temperature shown in a NASA's sounding rocket test data was reproduced with CFD technique, comparing with those with analytical method CFD made heat transfer rates and recovery temperatures as the flight trajectory, which made it possible to calculate the wall temperature of rocket. The predicted wall temperature was compared with analytically predicted temperatures. Both the temperatures were compatible although their recovery temperature and heat transfer rates are a little different.
