The reynolds-averaged navier-stokes equations, together with the transport of energy equation, were solved in a time-dependent form to simulate passenger compartment cooling. The effect of air density variation due to temperature was included as a buoyant force term in the analysis through a boussinesq approximation. These transport equations were discretized, based on a finite volume method in a transformed domain. A general-body fitted curvilinear co-ordinate system was used to model interior geometries in the passenger compartment. The computational results for a j-car passenger compartment cooling showed overall flow information such as the propagation of cold air fronts, turbulent jet penetration and mixing, and buoyance-induced recirculating flows. Comparison of the available experimental data with predictions using isothermal wall boundary conditions showed excellent agreement in the prediction of the front breath-level temperature.
