Three-dimensional Navier-Stokes simulation for passenger compartment cooling
by T. Han
International Journal of Vehicle Design (IJVD), Vol. 10, No. 2, 1989

Abstract: 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.
