Abstract

In this study, a 3-D flame cooling analysis is conducted to examine thermal safety for the flame deflector of the 75 tonf class propulsion test facility, and the safe discharge of the exhaust gas is assessed by using numerical results. The Mixture multiphase model is adopted for the simulation of heat transfer and phase exchange process between flame and cooling water, and the computational study using the single species unreacted model for the exhaust plume is carried out for the flame cooling. Numerical analysis predicts maximum temperature on the flame deflector wall for different water flow rates, and evaluates the safe minimum flow rate of water corresponding to the fire-resistant temperature for concrete.

본 연구에서는 75톤급 추진기관 시험설비 화염유도로 설계안에 대한 열적 안전성 및 연소가스의 안전한 배출을 평가하기 위하여 3차원 화염냉각해석을 수행하였다. 화염과 냉각수 간의 열전달 및 상변화 과정을 모사하기 위하여 Mixture 다상모델을 적용하였으며, 단일 화학종 비반응 플룸모델을 이용한 화염냉각해석을 수행하였다. 본 해석결과를 통하여 냉각수 유량에 따른 화염유도로 벽면에서의 최고 온도값을 예측하였으며, 또한 콘크리트 내화온도에 해당하는 최소 냉각수 유량을 도출하였다.
