First of all, I am not a physicist, and no expert on aerodynamics, so bear over with me if this is a stupid question: Is the nose-cone design on the Model S the best solution to reduce the drag coefficient? The nose cone has a smooth surface. While this may appear to be optimal with regards to the drag coefficient, I am not completely convinced. Take the golfball example. I found this explanation online: “The surface of a golfball is made of small dimples. These dimples acts as “turbulators” and induce turbulence in the layer of air next to the ball. In some situations, a turbulent boundary layer reduces drag. There are two types of flow around an object: laminar and turbulent. Laminar flow has less drag, but it is also prone to a phenomenon called "separation." Once separation of a laminar boundary layer occurs, drag rises dramatically because of eddies that form in the gap. Turbulent flow has more drag initially but also better adhesion, and therefore is less prone to separation. Therefore, if the shape of an object is such that separation occurs easily, it is better to turbulate the boundary layer (at the slight cost of increased drag) in order to increase adhesion and reduce eddies (which means a significant reduction in drag). Dimples on golf balls turbulate the boundary layer.” We know that a dimple-less golf ball will only travel half the distance of a normal golf ball. Could the same aerodynamic principle be used by designing the Model S nose cone with dimples? Other car-manufactorers have never been able to do this because the air intake at this place makes this impossible. But the Model S could. ( And it might look pretty cool ) I am probably completely wrong, but explain me why.
