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…

Periodic boundary conditions on staggered grids: Uniqueness of variables at cell edges/faces
Divyanshu Gola
Periodic boundary conditions when applied to staggered grids, which define variables on both cell edges and cell centers, can be shown to have a problem with uniqueness of variable…

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…
