I have a few questions related to downforce in cars. Please forgive any fundamental misunderstanding of aerodynamics.
- Does the shape of a car, say a Volkswagen Golf, driving on a road produce lift or downforce?
- Is the Coanda Effect at play there?
- How does the height of the car above the ground affect the lift or downforce?
- Can the basic shape (i.e. airfoil) of the car be manipulated to produce downforce, perhaps by changing the angle of attack (e.g. lowering the front of the car)?
- When the air hits the front of the car, is it not redirected to a smaller area underneath the car, causing it to accelerate? Is this an example of the Venturi effect, causing downforce?
