Simulation and Experimental Research on Fluid Fields of the Refrigerated Truck

With the aid of computational Fluid Dynamics technique, the K-ε turbulence model is adopted to simulate the three-dimensional static airflow and temperature distribution inside the refrigerated truck on the platform of FLUNET, and the reliability of the simulation was certificated with the experiments. The result shows that the temperature of compartment entrance is lowest and while behind the body is the highest. Besides, it also shows that proliferation of the heat flow in vertical direction is obvious quicker than in horizontal direction and the gradient of temperature change is quite obvious near the side of bodywork.
