The work aims to review the present situation of CFD’s (Computational fluid dynamics) application in the food cold chain at home and abroad. The application of CFD in four stages of food cold chain: pre-freezing, freezing, cold storage and refrigerated transportation was discussed by classification. The researches and development of the application of CFD in food cold chain equipment were summarized, and the future development direction was pointed out. CFD numerical simulation technology is widely applied in the food cold chain and the flow field in the cold chain equipment is simulated and analyzed through CFD numerical simulation technology, which provides important significance for the optimization of cold chain equipment and the reduction of equipment energy consumption.
