Fish Meat Freezing with considering temperaturedependent thermal properties: A Numerical Study

Meat quality particularly is affected by the method or the cooling systems, which applied in freezing process. According to applying freezing method in most industry especially when the temperature difference is very high value, in this regard, analysis the efficacy of the changing of properties in freezing process is very important issue. Applying the computational fluid dynamic model (CFD), which can simulate the effect of freezing on meat properties, will help to save in time and cost. Especially when predicting the time for freezing the product with certain thermal properties. In this paper, CFD models created in two-dimensional in order to simulate the cooling process in terms freezing tunnel of refrigerator. Obtained Numerical results were compared with experimental data. The geometric of fish meat has been modeled and required time for freezing each of them has been obtained and compared with together. The storage temperature of each of meat was found from tables and handbooks and applied in simulation. The level of freezing in different times has been presented in temperature and freezing mass fraction counters. This condition validates by comparing the experimental and obtained data for fish meat. In addition, it is noticeable that freezing temperature for various meats is different from each other
