I am currently trying to find the force acting on a component that will be attached to a airplane wing using fluid dynamics (Drag force= 0.5*density*Drag Coefficient*A*v^2) and checking my results with FloWorks. I started with a simple sphere which I know I can calculate correctly analytically and comparing the results to the results from FloWorks. The results are different and my question is what am I doing wrong.
-Air as the fluid
-Velocity of 50 m/s
-Global goal (Force in the direction of flow)
The only thing I could think of is that selecting the global goal is only accounting for normal forces and not shear forces but I'm not sure how FloWorks works.....?
Any help would be great.
