Spatial Features of Reynolds-Stress Carrying Structures in Turbulent Boundary Layers with Pressure Gradient
M. Ali Yesildag, Taygun R. Gungor, Ayse G. Gungor +1
We investigate the Reynolds-shear-stress carrying structures in the outer layer of non-equilibrium pressure-gradient turbulent boundary layers using four direct numerical simulatio…
The three effects of the pressure force on turbulent boundary layers
Taygun Recep Gungor, Ayse Gul Gungor, Yvan Maciel
This study aims to isolate the three effects of the pressure force on the inner and outer layers: the local direct impact (characterized by the pressure gradient (PG) parameter, $Î…
Turbulent boundary layer response to uniform changes of the pressure force contribution
Taygun R. Gungor, Ayse G. Gungor. Yvan Maciel
We investigate a turbulent boundary layer (TBL) with uniform pressure force variations, focusing on understanding its response to local pressure force, local pressure force variati…
Turbulent activity in the near-wall region of adverse pressure gradient turbulent boundary layers
Taygun R. Gungor, Yvan Maciel, Ayse G. Gungor
Two direct numerical simulation (DNS) databases are investigated to understand the effect of the outer-layer turbulence on the inner layer's structures and energy transfer mechanis…
