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…
