Dynamics of large-scale quantities in Rayleigh-Bénard convection
Ambrish Pandey, Abhishek Kumar, Anando G. Chatterjee +1
In this paper we estimate the relative strengths of various terms of the Rayleigh-Bénard equations. Based on these estimates and scaling analysis, we derive a general formula for t…
Energy Spectrum of Buoyancy-Driven Turbulence
Abhishek Kumar, Anando G. Chatterjee, Mahendra K. Verma
Using high-resolution direct numerical simulation and arguments based on the kinetic energy flux , we demonstrate that for stably stratified flows, the kinetic energy spectrum…
A Shell Model for Buoyancy-Driven Turbulence
Abhishek Kumar, Mahendra K. Verma
In this paper we present a unified shell model for stably stratified and convective turbulence. Numerical simulation of this model for stably stratified flow shows Bolgiano-Obukhbo…
