冷冻过程中食品表面混合对流换热的数值分析

Numerical Analysis of Mixed Convection Heat Transfer on Food Surface in Freezing

用龙格一库塔法进行了混合对流换热的数值求解，结合食品冷冻分析了数值计算结果，探讨了食品冷冻中冷风的合理流向。

This paper describes using the Runge-Kutta method to carry on numerical calculation about mixed convection heat transfer, and analyses the result combining with the process of food freezing. The article also discusses reasonable flowing direction of cdd air in food freezing.
