Results with blowing control system


INFLUENCE OF THE BLOWING VELOCITY PARAMETER

Simulation done with the blowing velocity equal to the velocity inlet



       



    Although we got very good results with the blowing velocity equal to the velocity inlet, the results that we get with the blowing velocity equal to twice the flow velocity are not what we expected as you can see in the figures below.

DRAG COEFFICIENT "Cx"

    The value of the drag Coefficient Cx is independant of the flow features around the car. It does not depend on the velocity of the flow but it does depends on whether we apply the control system or not.
The approximated value of Cx without the blowing system is 0.0112 and the value with the control system is about 0.0106 with
Vs=Vo and about 0.012 with Vs=2Vo.
