| Abstract: | Five parts including air supply duct,air supply structure,air curtain,air return structure and air return duct were integrated and the modified two fluid model was employed to simulate the air flow and heat transfer in a display cabinet with central air supply.The temperature field characteristics were analyzed and the predicted temperatures were compared with measurements by experiments.The Comparisons showed that the predicted temperatures are agreement with the measurements,which means the integrated CFD... |
