Abstract

  The understanding of the flow field inside the cold store is very important to food storage at low temperatures. Transport phenomena, comprising airflow, heat and mass transfer, are key processes in refrigerated storage. This paper gives a review of approaches to modeling transport phenomena in food bulks, packages and stacks. A transient three-dimensional CFD model was developed to calculate the velocity, temperature and moisture distribution in an existing empty and loaded cool store. The dynamic behavior of the fan and cooler was modeled. The model accounted for turbulence by means of the standard k-3 model with standard wall profiles. The model was validated by means of velocity, air and product temperature. The airflow model is based on the steady state incompressible, Reynolds-averaged Navier-Stokes equations. The turbulence is taken into account using a k-α model. The standard as well as the Renormalization-Group (RNG) version of the k ÿ "model is investigated. The forced-circulation air cooler unit is modeled with an appropriate body force and resistance, corresponding to the characteristics of the fan and the tube-bank evaporator. The model was capable of predicting both the air and product temperature with reasonable accuracy.
