摘要

本文报道了考虑气流与模拟热电偶敏感元件的铜板之间的共轭传热的通道内超音速湍流的模拟结果。数值模拟进行了自由流马赫数\(\text{M}_{\infty }=3\), 4和5。结果表明，模拟结果与热风洞实验数据吻合较好。结果表明，在100 ms量级的时间内，与钢模型壁的共轭传热可以忽略不计。

NUMERICAL SIMULATION OF HEATING OF EXPERIMENTAL MODEL WALLS IN SUPERSONIC FLOWS

Results of simulations of supersonic turbulent flows in a channel with allowance for conjugate heat transfer between the air flow and a copper plate modeling the sensitive element of a thermocouple are reported. Numerical simulations are performed for free-stream Mach numbers \(\text{M}_{\infty }=3\), 4, and 5. It is shown that the simulation results agree well with experimental data obtained in a hotshot wind tunnel. It is found that the conjugate heat transfer with the model walls made of steel can be ignored at times of the order of 100 ms.
