The understanding of the flow field inside the cold store is very important to food storage at low temperatures. In this paper, the CFD simulation on the flow field for low temperature cold store with air forced supply mode is presented. The turbulence flow of three-dimensional steady incompressible viscous fluid is analyzed using finite volume method and standard K-ε two-equation. The temperature and velocity fields of this cold store are simulated, analyzed and compared. The simulation results show that the velocity and temperature fields are evidently influenced by the cross section from the ground, and the optimal cross section is also given in this paper.
