To echo Nick's comments. There's no need for Mechanical here. 

Flow around the cylinder is done in Fluent, and have a look at the NACA wing for some ideas about compressible flow. The cooling will also come from that, but you will need to decide on your initial conditions. Ie do you cool from a stationary point or assume it's at Mach 0.5 and then cools?
