Visualisation of Laminar Seperation Bubble Over an airfoil

Hi all,
I'm trying to visualize the laminar separation bubble formed over thicker airfoils at low Reynolds number and see how this affects the overall performance of the airfoil using Fluent. I used Gambit to mesh the airfoil and ran it on Fluent. However, I'm going terribly wrong somewhere and I'm doubting my initial assumptions. I would like to know: *If the problem can be solved on a laminar based model. Given that the bubble denotes a transition region and the region after reattaching(if it happens), is turbulent. *If laminar model can not be used, which other model is best shot at a decent solution? I've gone through a few papers on the same which did nothing more than add to my confusion. I would really appreciate it if someone explains these different models and what they are suited for. *If i ever will get a decent solution from Fluent? *What kind of mesh in general is best suited for the same? Spare me if my queries sound timid, I'm a complete newbie to all this! |
