表面传热率已被测量超过70度球形钝锥选择作为测试用例模型，以提供实验和计算数据库。在稀薄艾德和高超音速条件下，测量了沿着模型的加热率分布，并给出了攻角从0 °到30 °的变化。在SR3装置中，在自由飞行马赫数接近20的条件下进行了试验。考虑了三种气流稀薄情况，它们对应于雷诺数1420、4175和36265。雷诺数的计算使用自由状态条件和模型底部直径。在实验工作的同时，一个国际研究小组在相同的测试条件下进行了计算。实验和计算的加热速率之间的比较。
Surface heat transfer rates have been measured over a 70-deg spherically blunted cone chosen as a test case model to provide both experimental and computational databases. Under raree ed and hypersonic conditions, heating rate distributions are measured along the model and presented at angles of attack varying from 0 to 30 deg. Experiments have been conducted in the SR3 facility at a freestream Mach number close to 20. Three e ow rarefactions have been considered, which correspond to Reynolds numbers of 1420, 4175, and 36,265. Reynolds numbers are calculated using freestream conditions and the model base diameter. In parallel to the experimental work, e ow calculations were executed by an international group of researchers for identical test conditions. Comparisons between experimental and computational heating rates are also presented.
