WebAug 11, 2024 · For this either the Slip or the Freestream boundary can be selected. However, for some cars the undertray or wings are too close to the street because of which the the air velocity underneath the car can differ from the free stream velocity. This results in a speed difference that can create a boundary layer for the air underneath the car and ... WebVelocity at two different positions were measured for nitrogen flow case. The static pressure for air and nitrogen flow case were ∼1.3 kPa (10 torr) and ∼1 kPa (8 torr), respectively. citofono in english
