Spatiotemporal spectral transfers in fluid dynamics
Avik Mondal, Andrew J. Morten, Brian K. Arbic +3
Motivated by previous work on kinetic energy cascades in the ocean and atmosphere, we develop a spatio-temporal spectral transfer tool that can be used to study scales of variabili…
Hidden mechanism of dynamic large-eddy simulation models
Xiaohan Hu, Keshav Vedula, George Ilhwan Park
The dynamic model is one of the most successful inventions in subgrid-scale (SGS) modeling as it alleviates many drawbacks of the static coefficient SGS stress models. The model co…
Revisiting Crossflow-Based Stabilization in Channel Flows
Muhammad Abdullah, George Ilhwan Park
Stabilization schemes in wall-bounded flows often invoke fluid transpiration through porous boundaries. While these have been extensively validated for external flows, their effica…
Linear Stability Analysis of Oblique Couette-Poiseuille flows
Muhammad Abdullah, George Ilhwan Park
We perform a detailed numerical study of modal and non-modal stability in oblique Couette-Poiseuille profiles, which are among the simplest examples of three-dimensional boundary l…
