DDES-SSMBetter predictions: drag and pitching. Negative minimum pitching moment occurs at maximum lift. |
RANS, DDES-MaxDeep stall not captured. Fail to capture drop in pitching moment and increase |
DDES-SSM
- Substantial cycle-to-cycle variation near stall and down stroke
- Variations similar to experimental data
- Two lift peaks: secondary and primary peaks of the same order
- Multiple dynamic stall vortices just like the experiment
