I am a new memeber here and have some problems about the Fluent.
velocity of freestream is 20m/s,incompress flow ,AOA is 5deg question is: 1. I used the C topology grid around the airfoil. which boundary condition is better?the picture1 or the picutuer 2? is there any other good choice? 2. I want calcuate the cl and cd of E387 under the Re =1e5 with the SST k-w and S-A turbulence model y+=1 use boundary function y+=1 don't use boundary functon y+=30 use the boundary function which one is better? Need your help |
