Numerical Simulation on the Airflow Field and Heat Transfer in Large Cold Store

Abstract

A steady three-dimensional CFD model was developed to investigate the flow field in cold store, including velocity, temperature, and turbulence intensity distribution. The simulation was conducted on the example of the experimental cold store, considering both the empty case and the case fulfilled with packaged pork. According to different scales between cold store and single packaged food product, special vvvvattention has been given to the mesh quality and modelling of heat transfer at the surface of single product. The comparisons between two cases were performed in order to indicate further improvements to the arrangement of products.
