I'm working on a project that will find the coefficient of drag on bombs with various added drag features by modeling flow over the bomb at various angles of attack using CFD.
The problem is that I'm not sure if bombs with fins rotate while they are falling due to gravity, and if so, how I can relate the velocity of the flow to the rotation rate of the bomb.
Since the fins on a bomb are flat and not curved like an impeller, do they simply keep the bomb flying on a predictable path?
