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…
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…
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…
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…
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 re…
Upstream history quantification and scale-decomposed energy analysis for weak-to-strong adverse-pressure-gradient turbulent boundary layers
Atharva Mahajan, Rahul Deshpande, Taygun R. Gungor +2
The present study delineates the effects of pressure gradient history and local disequilibration on the small and large-scale energy in turbulent boundary layers (TBLs) imposed wit…
Effects of Reynolds number and spatial resolution on the pressure source terms in turbulent boundary layers
Aditya Agarwal, Rahul Deshpande
The increase in wall-pressure fluctuations with increasing friction Reynolds number () of a turbulent boundary layer (TBL) is well known in the literature. However, very few…
Response of a turbulent boundary layer to steady, square-wave-type transverse wall-forcing
Max W. Knoop, Rahul Deshpande, Ferry F. J. Schrijer +1
This study investigates the spatial evolution of a zero pressure gradient turbulent boundary layer (TBL) imposed by a square-wave (SqW) of steady spanwise wall-forcing, which varie…
Streamwise energy-transfer mechanisms in zero- and adverse-pressure-gradient turbulent boundary layers
Rahul Deshpande, Ricardo Vinuesa
The present study investigates streamwise () energy-transfer mechanisms in the inner and outer regions of turbulent boundary layers (TBLs). Particular focus is plac…
