Fluent Airfoil Analysis

August 25, 2003, 19:03

I would like to study airfoil characteristcs in fluent. I have coordinate data for the airfoils. I want to study low reynolds number lift and drag performance (coefficients). Any suggestions?

sure..why not..i do the same thing, draw in gambit then export to fluent

i have a trouble modeling an airfoil -selig1223 high lift device- at laminar regime -Re=150000-, because in the tutorials of fluent appears models at transonic regime (turbulence regime) but nothing about a laminar regime -and their appropiate boundary conditions-... my trouble is i model these airfoil using laminar solver -without turbulence model- but the residuals monitor never gives convergence... and if i use S-A turbulence model to solve it, the residuals, lift and drag monitors gives convergence but the results are not the same as experimental data... i.e exp lift=1.3, fluent lift=1.4 :s any suggestion please? because is obviously that i am wrong

p.d this is the airfoil http://www.nasg.com/afdb/show-airfoil-e.phtml?id=1021

Anyone have the tutorial for the 3d analysis of the aerofoil in FLUENT?I already assemble my model in GAMBIT and all I need is to analyze it in FLUENT.Please someone help me.
