Hi..
I'm doing a cfd analysis of a 3d airfoil under a specific inlet velocity via fluent. I did the simulation for two different airfoils the only difference being that one airfoil is geometrically scaled by a factor of 100. But the coefficient of lifts of both the models are different by an order of e05, with the upscaled airfoil having a larger lift coeff. The wind speed, parameters, airfoil shape are all exactly the same. The only difference is that one is scaled. I don't understand why I'm getting a different lift coefficient. I don't know what i'm doing wrong. Please Help. Original(B).jpg Scaled(D).jpg |

Hi Gohan,
Could you find a solution for your problem? Because I have similar problem, and I'm still looking for any reason for what could cause that much difference. |
