Scale interactions and energy transfer in the turbulent wake of a bluff body
Jinyuan Liu, Sutanu Sarkar
Turbulent bluff-body wakes exemplify the coexistence of large-scale coherent structures and fine-scale turbulence -- two ends of a wide dynamical range of scales connected through…
Tidally dominated flows past a three-dimensional topography: Wake vortices, turbulence, and mixing
H. M. Aravind, Pranav Puthan, Sutanu Sarkar +2
Oceanic turbulence influences the transport and mixing of freshwater, heat, nutrients, and other biogeochemical tracers. It also has broader implications for oceanic and atmospheri…
Turbulence in stratified rotating topographic wakes
Jinyuan Liu, Pranav Puthan, Sutanu Sarkar
Turbulence generation mechanisms in stratified, rotating flows past three-dimensional (3D) topography remain underexplored, particularly in submesoscale (SMS) regimes critical to g…
Stratified wakes of a prolate spheroid at moderate angle of attack
Sheel Nidhan, Sanidhya Jain, Jose L. Ortiz-Tarin +1
Ocean submersibles and aerial vehicles often encounter a density-stratified environment whose effect on flow features is of interest. A 6:1 prolate spheroid of diameter with ve…
