Abstract
The present paper deals with the two-dimensional and threedimesnional flow fields within automobile passenger compartments. They are studied by solving the incompressible Navier-Stokes equations numerically. The computational procedure employs a 3rdorder upwind scheme which has been proved to be very effective for the analysis of high-Reynolds-number flows. Furthermore, the Boussinesq approximation is employed because the present cases treat flows with small temperature difference.
The output of the computation is introduced into an en gineering work station, and displayed using color graphics or animations. It is shown that the computed results for twodimensional velocity fields are in good agreement with the twodimensional experimantal data. As far as the temperature fields are concerned it seems that heat transfer is generated by vortex convection.
