Leveraging modal structure similarity for simulation of spatially evolving wakes
Divyanshu Gola, Sutanu Sarkar
We present a new methodology to enable efficient simulation of high Reynolds number wakes. In this approach, a body-exclusive hybrid simulation at Re = 5 x 10^4 is initialized usin…
Internal gravity waves in flow past a bluff body under different levels of stratification
Divyanshu Gola, Sheel Nidhan, Sutanu Sarkar
The flow field of a bluff body, a circular disk, that moves horizontally in a stratified environment is studied using large eddy simulations (LES). Five levels of stratification (b…
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…
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…
