Dear folks,
I want to simulate a problem with a elliptical airfoil with a = 0.5m, b = 0.05m. 1) Because of the data from the literature is based on Re = 500 (corresponding to the chord length of the airfoil), I change everything of the material to 1, i.e., density = 1kg/m^3, and change the viscosity of the material to 0.002. Is that a good way to do this kind of simulation? Also, I change everything in Reference Value to their number also. (all = 1, except the viscosity) 2) After I did what I described, I found the histories of lift & drag coefficients are not that good for comparison. Do I need to change the Reference values of area to some value rather than 1m^2? thanks in advance. Last edited by zhenglun.wei; May 7, 2011 at 22:33. |
