axial flow around a cylinder -heat transfer model?
I am to model the axial flow around a cylinder (air, incompressible, steady, high turbulent flow). The cylinder is hot so there is a heat transfer to the fluid. Now I have some questions:
What is the best turbulence model? How to choose grid size ant type at the boundary layer? should I use a wall function???
I want to compare it to experimental values, but it is very hard to find any appropiate reference for AXIAL flow... any sugestion???

Have a look the recent two papers and refernce therein, you might get few things of your interest
. Fetecau, C., Fetecau, C. (2005) On some axial Couette flows of non-Newtonian fluids, Zeitschrift fur Angewandte Mathematik und Physik 56 (6), pp. 1098-1106
