【 摘 要 】

Thermal entrainment factor (TEF) is an important parameter to describe the cold preservation performance of a display cabinet. In order to calculate the TEF of a display cabinet rapidly and accurately, the method of establishing a correlation model based on computational fluid dynamics (CFD) simulation results is presented and the correlation model of TEF for typical single air curtain is developed in this paper. The TEF for single air curtain without back panel airflow can be regressed by an exponential function of Reynolds number and deflection modulus.
