Reynolds-number scaling of wall-pressure--velocity correlations in wall-bounded turbulence

Woutijn J. Baars, Giulio Dacome, Myoungkyu Lee

Wall-pressure fluctuations are a practically robust input for real-time control systems aimed at modifying wall-bounded turbulence. The scaling behaviour of the wall-pressure--velo…
