Development of an Aerodynamic Prediction Using an Advanced Aerodynamic Panel Program 2002-01-2045

An advanced panel method is presented for simulating the airflow of arbitrary three-dimensional automotive body in the paper. The theory is about a wake synthesizer for panel methods that use an iterative procedure to determine the position of strongly interacting vortex sheets. The estimation of the wake geometry is based on blunt body theory with separation flow. The method is applied to the A-pillar separation on foreside of an automobile and be fit for determine the starting point for a three-dimensional iterative solution. Comparison with experimental data shows that calculations results with the estimated wakes are more reality than with the attached flow
