I feel that
1. You didn't show the pressure gradient contour, acoording to the velocity contour, looks like there's reverse flow(not very clear) on upper surface, so the flow seperated.It means the LIFT FORCE will drop. Its shape should be more streamlined.
2. The stagnation area is too large, try to reduce the stagnation area (more streamlined shape required) to drop FORM DRAG
3. If you encountered reversed flow, what's your turbulent model? (K-e is not suitable for this)
It's better to be Menter's SST(shear stress transfer) model. |
