A technique based on Lattice Boltzmann Method has been applied to the aerodynamic noise simulation by calculating the surface pressure fluctuations. In the first place, basic investigations were performed by using a simple geometry model (wedge box) that generated the flow structure similar to that of vehicle's A-pillar vortex. Then, the work was extended to an actual production vehicle's body. As a result, the tendency of the surface pressure fluctuations around A-pillar was captured. Consequently this method makes it possible to evaluate the complex flow pattern and the surface noise signature at the early exterior design phase without wind tunnel tests using prototype vehicles.
