Disk wakes in nonlinear stratification
D. Gola, S. Nidhan, J. L. Ortiz-Tarin +2
Nonlinearity of density stratification modulates buoyancy effects. We report results from a body-inclusive large eddy simulation (LES) of a wake in nonlinear stratification, specif…
The high-Reynolds-number stratified wake of a slender body and its comparison with a bluff-body wake
J. L. Ortiz-Tarin, S. Nidhan, S. Sarkar
The high-Reynolds number stratified wake of a slender body is studied using a high-resolution hybrid simulation. The wake generator is a 6:1 prolate spheroid with a tripped boundar…
Modal analysis of bluff body wakes
Sheel Nidhan, Divyanshu Gola, Sutanu Sarkar
Spectral proper orthogonal decomposition (SPOD) analyses are performed for unstratified and stratified wakes of a circular disk at Reynolds number, , where $U…
The high-Re far wake of a slender body and the effects of density stratification
J. L. Ortiz-Tarin, S. Nidhan, S. Sarkar
The high-Reynolds-number wake of a slender body with a turbulent boundary layer is investigated using a hybrid simulation. The wake generator is a 6:1 prolate spheroid and the Reyn…
