A diffuser is used to decelerate the air flow entering an engine. The performance of a diffuser is measured by the pressure gradient across the diffuser and is determined by the divergence angle. The maximum divergence angle of a diffuser is limited by flow separation. In this project, a "bump" will be placed in the diverging wall of the ...

Rear Diffuser angles - TenTenths Motorsport Forum

Sep 26, 2008· This void is in fact acting as a diffuser and will allow the floor area of the car to give downforce. A correctly designed diffuser 'tidies up' this area and matches the pressure under the car more accurately to the pressure behind the car. The angle in the diffuser is to prevent seperation and the resulting turbulence and drag.

With this in mind, the role of the diffuser on a racing car is to speed the airflow up underneath the car, reducing its pressure, creating a greater difference in pressure between the upper and lower surfaces of the car. This means more downforce and aerodyamic grip, allowing the car to corner faster.

What Is The Function of A Car Rear Diffuser? - Winn Autosports

Jan 16, 2019· As the low-pressure air reaches the rear portion of the vehicle, through the car rear diffuser, it expands in an expansion chamber. When the air expands, the Venturi effect takes place, where the air pressure is increased and the airspeed is reduced, significantly.

Wing-Diffuser Interaction on a Sports Car

Furthermore, on most race cars, a wing is mounted at the rear end. Since the rear wheels and wing will influence the base pressure it is believed that, for a modern race car, there could be a strong interaction between these items and the diffuser.

How the Diffuser, Exhaust and Rear Wing Creates Downforce ...

The job of the diffuser is to diffuse the high velocity air flow running under the car to the rear of the car so that the air flow moves closer to that of ambient pressure. With the diffuser working, an F1 car turns into a venturi tube which is the most efficient aerodynamic package on an F1 car to create downforce.
