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…
Assessment of non-intrusive sensing in wall-bounded turbulence through explainable deep learning
A. Cremades, R. Freibergs, S. Hoyas +3
In this work we present a framework to explain the prediction of the velocity fluctuation at a certain wall-normal distance from wall measurements with a deep-learning model. For t…
Bursting bubble in an elasto-viscoplastic medium
A. G. Balasubramanian, V. Sanjay, M. Jalaal +2
A gas bubble sitting at a liquid-gas interface can burst following the rupture of the thin liquid film separating it from the ambient, owing to the large surface energy of the resu…
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…
Active and inactive contributions to the wall pressure and wall-shear stress in turbulent boundary layers
Rahul Deshpande, Ricardo Vinuesa, Joseph Klewicki +1
A phenomenological description is presented to explain the intermediate and low-frequency/large-scale contributions to the wall-shear-stress () and wall-pressure () sp…
Characteristics of active and inactive motions in high-Reynolds-number turbulent boundary layers
Rahul Deshpande, Ricardo Vinuesa, Ivan Marusic
Wall-scaled (attached) eddies play a significant role in the overall drag experienced in high-Reynolds-number turbulent boundary layers (TBLs). This study aims to delve into the un…
