A source-term interpretation of turbulent rough wall-pressure spectra
J. M. O. Massey, A. J. Smits, B. J. McKeon
Wall-pressure fluctuations beneath a turbulent boundary layer drive the flow-induced noise and structural loading of rough surfaces. On a smooth wall their variance grows with the…
Two-component inner--outer scaling model for the wall-pressure spectrum at high Reynolds number
Jonathan M. O. Massey, Alexander J. Smits, Beverley J. McKeon
Wall-pressure fluctuations beneath turbulent boundary layers drive noise and structural fatigue through interactions between fluid and structural modes. Conventional predictive mod…
Spanwise wall forcing can reduce turbulent heat transfer more than drag
Amirreza Rouhi, Marcus Hultmark, Alexander J. Smits
Direct numerical simulations are performed of turbulent forced convection in a half channel flow with wall oscillating either as a spanwise plane oscillation or to generate a strea…
Wall-wake laws for the mean velocity and the turbulence
Alexander J. Smits
A new wall-wake law is proposed for the streamwise turbulence in the outer region of a turbulent boundary layer. The formulation pairs the logarithmic part of the profile (with a s…
