ABSTRACT

Numerical and experimental results made it possible to highlight the confinement effect due to enclosure and the influence of load permeability on the jet penetration, its development and hence the overall heterogeneity of ventilation within the truck. Within refrigerated vehicle enclosure, air is supplied at relatively high velocities through a small inlet section located adjacent to or near the ceiling. In the refrigerated enclosure, heat is transferred primarily by convection; therefore, the temperature and its homogeneity are directly governed by the patterns of airflow. According to the complexity of direct measurement of local air velocities within a refrigerated truck, computational fluid dynamics (CFD) has become the methodology of choice for the development of airflow models. According to the complexity of direct measurement of local air velocities within a refrigerated truck, CFD has become methodology of choice for the development of airflow models. Q. Zou, L. U. Opara, and R. A. Mckibbin developed CFD models of ventilated boxes undergoing forced-air cooling.
