HiLiftAeroML: A High-Fidelity Computational Fluid Dynamics Dataset for High-Lift Aircraft Aerodynamics
Neil Ashton, Adam Clark, Liam Heidt +13
HiLiftAeroML is, to our knowledge, the first open high-fidelity computational fluid dynamics dataset dedicated to high-lift aircraft aerodynamics. It contains 1,800 simulations spa…
Stratified wakes of a prolate spheroid at moderate angle of attack
Sheel Nidhan, Sanidhya Jain, Jose L. Ortiz-Tarin +1
Ocean submersibles and aerial vehicles often encounter a density-stratified environment whose effect on flow features is of interest. A 6:1 prolate spheroid of diameter with ve…
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…
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…
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…
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 $U…
The high-Re far wake of a slender body and the effects of density stratification
J. L. Ortiz-Tarin, S. Nidhan, S. Sarkar
The high-Reynolds-number wake of a slender body with a turbulent boundary layer is investigated using a hybrid simulation. The wake generator is a 6:1 prolate spheroid and the Reyn…
Analysis of coherence in turbulent stratified wakes using spectral proper orthogonal decomposition
Sheel Nidhan, Oliver T. Schmidt, Sutanu Sarkar
We use spectral proper orthogonal decomposition (SPOD) to extract and analyze coherent structures in the turbulent wake of a disk at Reynolds number and Frou…
Spectral POD analysis of the turbulent wake of a disk at Re = 50, 000
Sheel Nidhan, Karu Chongsiripinyo, Oliver T. Schmidt +1
The coherent structures in the turbulent wake of a disk at a moderately high Reynolds number ($\Rey$) of are examined using spectral proper orthogonal decomposition (SPOD)…
