Restoring Chaos Using Deep Reinforcement Learning
Sumit Vashishtha, Siddhartha Verma
A catastrophic bifurcation in non-linear dynamical systems, called crisis, often leads to their convergence to an undesirable non-chaotic state after some initial chaotic transient…

Large eddy simulations of turbulent thermal convection using renormalized viscosity and thermal diffusivity
Sumit Vashishtha, Mahendra K. Verma
In this paper we employ renormalized viscosity and thermal diffusivity to construct a subgrid-scale model for large eddy simulation (LES) of turbulent thermal convection. For LES,…
