Numerical Simulations of Wind Noise around an Automobile in a Crosswind
Wind noise increases and disturbs passenger comfort as crosswinds generally produce strong vortices around A-pillars and door mirrors. Aeroacoustics simulations using nonlinear equations split from compressible flow equations are performed to visualize how the wind noise is generated and propagates in conditions with/without a crosswind. Although the crosswind strongly increases wind noise from the A-pillar, the waves that reach the side window mainly originate from the door mirror and not the A-pillar. These directional characteristics of the wave emissions are demonstrated by drawing acoustic stream lines.
