High-Reynolds-number turbulent boundary layers under adverse pressure gradients. Part 1. Decoupling local and upstream pressure gradient effects
Ahmad Zarei, Mitchell Lozier, Rahul Deshpande +1
This study presents a controlled examination of the universality of the von Karman and additive coefficients in the logarithmic law of the mean streamwise velocity profile for high…
Defining the mean turbulent boundary layer thickness based on streamwise velocity skewness
Mitchell Lozier, Rahul Deshpande, Ahmad Zarei +3
A new statistical definition for the mean turbulent boundary layer thickness is introduced, based on identification of the point where the streamwise velocity skewness changes sign…
Turbulent/non-turbulent interface in high Reynolds number pressure gradient boundary layers
Ivan Marusic, Wagih Abu Rowin, Mitchell Lozier +3
We report two-dimensional particle image velocimetry experiments in high Reynolds number turbulent boundary layers imposed with a moderately strong streamwise pressure gradient. Th…
A note on the amplitude modulation phenomenon in non-canonical wall-bounded flows
Mitchell Lozier, Ivan Marusic, Rahul Deshpande
The amplitude modulation phenomena, defined originally by Mathis et al. (J. Fluid Mech., 628, 311-337; 2009), corresponds to a unique non-linear interaction between Reynolds number…
