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…
Transpose-free Fast Fourier Transform for Turbulence Simulation
A. G. Chatterjee, M. K. Verma, M. Chaudhuri
Pseudo-spectral method is one of the most accurate techniques for simulating turbulent flows. Fast Fourier transform (FFT) is an integral part of this method. In this paper, we pre…
