Table 2 Comparison of three transition detection methods
From: Experimental study on transition of dynamic airfoil in pitching oscillation
Method | Experimental time | Sampling | Accuracy of AoA | Feature detection |
|---|---|---|---|---|
PA | Long, Tens of minutes | Low, Hundreds of Hz | Low | General |
SWT | Short, Tens of seconds | High, Tens of kHz | Low | General |
VSWT | Short, Tens of seconds | High, Tens of kHz | High | Obvious |
