摘　　要：本文针对可重复使用热结构，计算研究了类前缘外形热结构防热层瞬态热响应问题，探索分析了前缘防热层的热响应特征．在计算中成功地实现了任意坐标变换下代数网格生成，并求解了任意坐标下的热传导方程，为进一步开展外流场／结构热响应全耦合一体化计算研究打下了基础．In this paper, the thermal response in the thermal protection layer of leading edge, which is usually used in reusable thermal structure, is numerically simulated. The arithmetic grid generation technique that is commonly used in computational fluid dynamics is successfully applied by introducing arbitrary- coordinate transformation in the present simulation. The numerical solution of the heat conduction equation is obtained, which is the basis of the computation coupling flow field with thermal response.
