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)
