Abstract
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.
