NUMERICAL INVESTIGATION OF HEAT AND MASS TRANSFER IN A REFRIGERATED TRUCK COMPARTMENT
Printer-friendly versionPDF version

This work aims at presenting a numerical model to simulate the temperature and velocity fields in back compartment of a refrigerated semi-trailer. The cavity is ventilated by means of a ceiling evaporator. The air flow and temperature distributions in this ventilated enclosure are analysed from a CFD model. This model focuses on the jet development in the empty cavity. The influence of heat flux through the walls on the air temperature fields is observed. A parametric study regarding the blowing velocity is also presented. It shows that changing the velocity does not noticeably modify the air flow structure inside the cavity. However when the length of the back compartment is increased, the flow structure changes. Finally the insulated wall is modeled and a new boundary condition is set with fixed external ambient temperature and convective heat transfer coefficient. Results show that the influence of external conditions on the temperature field is strongly reduced.
