esha Member Join Date: Aug 2018 Posts: 85 Rep Power: 7	Hi, I am trying to simulate 2D NACA0012 . I have fixed Re=1000. My mentor told me that Cd and Cl should be the same when we compare air or liquid by fixing Re. But I am getting problem while using water-liquid. I have viscosity 0.001003, density 998.2, c=1 and velocity is 0.001005 implies Re=1000. But the results are not same. Can anyone let me now where I am wrong. What should I do? Thank you!
