Evidence that superstructures comprise self-similar coherent motions in high Reynolds number boundary layers
We present experimental evidence that the superstructures in turbulent boundary layers
comprise smaller, geometrically self-similar coherent motions. The evidence comes from …

Generalization of the PIV loss-of-correlation formula introduced by Keane and Adrian
In 2D particle image velocimetry (PIV), the loss-of-correlation due to out-of-plane motion or
light-sheet mismatch has two effects. First, it reduces the probability of detecting a valid …
