I am working on naca0008 profile. using circular domain of radius 15. i have structured grid of 70400 node points at Re6000 in fluent. my proile drag validate but lift not validate.
i have change my domain to radius 30 but results are about same. quality is also good. i have check at alpha= zero and 4 degree. in both case drag validate but lift not. Solution methods are Prssure velocity coupling Scheme Fractional step Gradient Least square cell based pressure- standard momentum- Quick Second order Implicit-- Non iterative time Advancement Time step size 0.001 Please See my problem and give suggestion about lift as i got lower (less than half of the lift) |
