Wall-scaled eddies and embedded shear layers in high-Reynolds-number moderate adverse-pressure-gradient boundary layers
Ahmad Zarei, Mitchell Lozier, Ivan Marusic +1
This study compares high-Reynolds-number turbulent boundary layers under zero and low-to-moderate adverse pressure gradients, showing similar scaling and energy contributions from…
Response of a Turbulent Boundary Layer to a Synthetic Periodic Large-Scale Structure
Mitchell Lozier, Flint O. Thomas, Stanislav Gordeyev
The dynamic response of a zero-pressure gradient turbulent boundary layer (TBL) to a large-scale perturbation in the outer region was investigated experimentally. The baseline TBL…
On the wake region of high-Reynolds-number turbulent boundary layers subject to adverse pressure gradients
Mitchell Lozier, Ahmad Zarei, Ivan Marusic +1
The effect of a moderate adverse pressure gradient (APG) on the structure of a high-Reynolds-number turbulent boundary layer (TBL) was investigated experimentally using complementa…
High-Reynolds-number turbulent boundary layers under adverse pressure gradients. Part 2. A composite mean velocity profile
Ahmad Zarei, Mitchell Lozier, Rahul Deshpande +1
A robust composite mean velocity profile is developed for turbulent boundary layers (TBLs) subjected to adverse pressure gradients (APGs), extending the composite formulation for g…
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…
Spatial input-output analysis of large-scale structures in actuated turbulent boundary layers
Chang Liu, Igal Gluzman, Mitchell Lozier +4
This paper develops a spatial input-output approach to investigate the dynamics of a turbulent boundary layer subject to a localized single frequency excitation. This method uses o…
