3d flow simulation of staggered fin tube heat exchanger
 

hi,
i am analysing 3d flow of fin tube heat exchanger staggered arrangement. in that air will be send as a coolent b/w two fins(fin pitch).. and by considering tubes as a wall and fins also as wall .....how to find 'convective heat transfer coefficient" of airside in fuent...i am struggling to find....please help me in this... and suggest if different methods are available in fluent to find that heat transfer coefficient....i am eager to kneww this....please help....
