[color=#FF8000]I’m going to keep this short and simple.
[b]This is Graham Feltham. He is an Aerospace Engineer and currently he is working at the Experimental Fluid Dynamics Lab at University of Toronto. The interesting thing about this is that he has access to a water tunnel. The tunnel has the same function as the wind tunnel used by car manufacturers, but instead of wind the object is submerged in water and the smoke is replaced by bubbles, created from the electricity running trough a thin wire.
He uses the tunnel to explore the aerodynamics of different cars as well as specific aero parts such as spoilers, lips, diffusers etc. So go over there and give it a look [/b]
