| 摘 要： | 本文采用控制容积法,光线踪迹法结合谱带模型,研究航天飞机返回大气层时舷窗硅玻璃的非稳态复合换热。文章给出了界面S_2处于第三类非线性边界条件下,舷窗硅玻璃内部的温度场和进入机舱内部的热流密度。计算结果表明,如不考虑硅玻璃内部的辐射作用,对温度场影响不太大,但对进入机舱内的热流密度将会产生很大的误差。

| Abstract: | In this paper, the transient combined heat transfer in the silicon glass porthole of space shuttle is studied by control volume method, ray tracing method and spectral band model. The temperature field in the silicon glass and heat flux entering the space cabin are given under the 3rd kind nonlinear boundary condition. The computation results show, if the radiation in the silicon glass is omitted, the errors for temperature fields are not too evident, but for heat flux are quite large. |
