Measurements of non-linear energy transfer in canonical and drag-reduced turbulent boundary layers
Max W. Knoop, Bas W. van Oudheusden, Rahul Deshpande
Three-dimensional particle-tracking velocimetry (3D-PTV) measurements were used to compute the spectral transport of the Reynolds-stress tensor. The experimental framework is valid…
Wall-scaled eddies and embedded shear layers in high-Reynolds-number moderate adverse-pressure-gradient boundary layers
Ahmad Zarei, Mitchell Lozier, Ivan Marusic +1
The paper investigates how high‑Reynolds‑number turbulent boundary layers behave under zero and moderate adverse pressure gradients, revealing that additional energy in the outer r…
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…
Convection velocities and velocity coupling of outer-scaled wall-pressure fluctuations in canonical turbulent boundary layers
Rahul Deshpande, Abdelrahman Hassanein, Woutijn J. Baars
This study shows that the turbulent velocities most strongly correlated with outer-scaled (-scaled) wall-pressure fluctuations beneath a zero-pressure-gradient boundary layer r…
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…
On the wall-normal velocity variance in canonical wall-bounded turbulence
Michael Heisel, Rahul Deshpande, Gabriel G. Katul
The variance and spectra of wall-normal velocities are investigated for direct numerical simulations of turbulent flow in a channel, pipe, and zero-pressure-gradient boundary layer…
