Application43 Flow Velocity of the Air around the Car

Fluid flow around the car behaves differently depending on its form, size, and materials.
Fig. 1 is an analysis model where the air domain is created around the automobile. The flow velocity is set from the front to the back of the car. Fig. 2 is the analysis results in the streamlines. Fig. 3 the results in the fluid velocity vectors. The results show the fluid velicity changes depending on the form of the model. It is confirmed that the flow swirls at the back of the model.
