Computation of External Automobile Body Shapes 932887
A new computational software system called UNIS which integrates grid generation, boundary condition and problem setup, flow simulation, data post-processing, and visualization has been used to compute three dimensional turbulent flow over three external automobile body shapes: (1) station wagon; (2) sedan; (3) sedan with wheels. A modified Baldwin-Lomax turbulence model was used. Surface pressure coefficients along several surface lines compare well with experimental data.
