Large-scale streaks in a turbulent bluff body wake
Akhil Nekkanti, Sheel Nidhan, Oliver T. Schmidt +1
A turbulent circular disk wake database (Chongsiripinyo \& Sarkar, \textit{J. Fluid Mech.}, vol. 885, 2020) at Reynolds number is inte…
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…
High drag states in tidally modulated stratified wakes
Pranav Puthan, Geno Pawlak, Sutanu Sarkar
Large eddy simulations (LES) are employed to investigate the role of time-varying currents on the form drag and vortex dynamics of submerged 3D topography in a stratified rotating…
Second Moment Closure Modeling and DNS of Stratified Shear Layers
Naman Jain, Hieu T. Pham, Xinyi Huang +3
Buoyant shear layers are encountered in many engineering and environmental applications and have been studied by researchers in the context of experiments and modeling for decades.…
Analysis of coherence in turbulent stratified wakes using spectral proper orthogonal decomposition
Sheel Nidhan, Oliver T. Schmidt, Sutanu Sarkar
We use spectral proper orthogonal decomposition (SPOD) to extract and analyze coherent structures in the turbulent wake of a disk at Reynolds number and Frou…
