I am pursuing my M.Tech thesis with the topic "Thermal analysis of cross flow around cylinders" using Fluent.

Please guide me that which boundry contion should I take at cylinder and at flow inlet.

I have done work on single cylinder using FLUENT. I had applied boundry condition on wall as T=1 & at flow inlet T=0 as I am doing nondimensional study (Re=100 and Pr=10). But in result, I am getting isotherm contours which are not proper. The result file for this isothermal contour is attached herewith.

Can anyone sort out the problem? Guide me plz...
