This should be a fairly easy problem, although my Heat Transfer is quite rusty. I'm trying to get a ballpark estimate for a rotating cylinder that has flow on both the inside and outside.
I know the temperature of the air at the inlet and outlet and am trying to get a decent estimation for the wall temp. I would be happy assuming that I'm doing a 1D problem at both inlet and outlet and then letting the numerical program converge the answer (more complex geometry than just cylinder).
I was treating this as basically a 1D wall problem with moving flow on both sides. I have velocities on both sides and am struggling with how to proceed. I'm looking through my textbook but can't seem to find a decent Nusselt number or anything. Maybe I'm looking in the wrong place though.
On second though, perhaps I can treat it as two separate "Flow over a Flat plate" problems and then just use each solution separately for heat transfer coefficients. From that point, I can just do a simple wall problem. Would this get my in the ballpark?
Thanks
