HiLiftAeroML: High-Fidelity Computational Fluid Dynamics Dataset for High-Lift Aircraft Aerodynamics
Neil Ashton, Adam Clark, Liam Heidt +11
This paper describes the first-ever open-source high-fidelity CFD dataset of a high-lift aircraft for the purpose of AI surrogate model development. The dataset is composed of 1800…
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…
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)…
