- Abstract
The physical models from the supermarket scale, open vertical refrigerated display cabinet to the shelf scale were built based on the system multiscale method, and the fluid flow and heat transfer character of three different scales were analyzed. The computational results showed the temperature and velocity fields had very good agreement among three scales. The average deviations of temperature and air velocity for the second shelf were 1.31 °C and 0.2 m/s, respectively. The multiscale method of the proposed system could correctly predict the temperature and velocity distribution from the supermarket space to inside of refrigerated display cabinet.
