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…

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…
