turbine wheel... rough or smooth?
« on: 31 May 2013, 15:16 »
will the turbine wheel flow better smooth or rough?

was thinking either smooth - the gases flow faster past
or
rough - more friction to help spin the wheel

thoughts please!!!!!

 :huh:

Smooth. Aerodynamics? Turbine wheels are probably designed to be the shape they are to spin.

Friction causes heat, which could have some detrimental affect, maybe?
