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…

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…
