Fluent-Flow over heated cylinder

Khyati

Hey Everyone,

I am trying to solve Flow over a heated cylinder in a contra Flow (vertically downward direction) using Fluent, at Re = 130 and Richardson number between 0.0. and 1.0. This arrangement also gives a buyancy driven flow. I had tried using the Boussineq approximation but didnt work. So I had to use density as a function temperature ands seems to give reasonable results for lower temperatures. But there are complications with the higher temperatures.

Is anyone solving a similar kind of problem using Fluent? If someone is I had a couple of doubts.

I would really appreciate any response regarding the same.

Thanks Khyati
