Based on the established virtual heat transfer test bench, the slit impact jet simulation of different structural parameters and injection parameters under actual industrial application was carried out based on the comparison with the experimental results, and the average heat transfer coefficient under different test conditions was obtained. Summarize the standard heat transfer equation of slit impact jet Nu = 0.254Re0.72 Pr0.42 Ar0.29 (H Dh) -0.14.
