Forget the CFD case. If you had to make some averages of some quantity varying in time... would you wait for it first reaching a statistically steady state? I think you know the answer (which, just...

I don't know this but certainly, if you agree with me on the derivation, it can't be different. What i'm sure of is that the tangential velocity is just a post-processing quantity and not a solved...

cos (theta) = x/r = x / sqrt(x^2 + y^2)

sin (theta) = y/r = y / sqrt(x^2 + y^2)

where theta is measured counterclockwise with respect to the positive x axis.

In this case the formula for...
