In order to calculate the TEF of a display cabinet rapidly and accurately, a correlation of TEF for air curtain in a horizontal display cabinet is developed based on computational fluid dynamics (CFD) simulation results in this paper. The TEF of display cabinet predicted by the correlation gives a maximum deviation of 11.7% and a mean deviation of -0.6% compared with the published experimental data, which indicates that the 参考文献 Navaz H K, Henderson B S, Faramarzi R, et al.
