2D modeling heat transfer surface
 

I am a mechanical engineering student in University Science Of Malaysia, Pulau Pinang. Recently i have receiveing a student project about modeling heat transfer surface which focus on research of radiator design. What i need to do is make an analysis about the fluid flow characteristics through louvers in 2-dimensions by using CFD software. I hope someone who experts in this analysis can give me some advise or guide for which software most suitable that can i used through this project analysis and the analysis procedure the i need to follow. Anyway that all,thanks. Any comments also can delivered via an e-mail :)
