수직 이착륙기의 고온 배기가스에 의한 함정 갑판의 열응력 계산을 위한 복합열전달 해석

초록

This study has analyzed the convective heat transfer on the deck exposed to the high-temperature impingement exhausting from a VTOL. The heat flow of the impingement on the deck is modeled by the convection heat transfer. The convective heat flux generated by the hot impinging jet is investigated by using both convective heat transfer formulation and conjugate heat transfer formulation. Computational fluid dynamics(CFD) code was used to calculate the convective heat transfer. The RANS equation and the k-e turbulence model were used to analyze the thermal flow of the impinging jet. The temperature distribution near the stagnation zone obtained by the conjugate heat transfer analysis shows more reasonable than the convective heat transfer analysis.
