Vortex structure in rotating Rayleigh-Benard convection [PDF]

, 1997
The authors investigate the flow patterns in a cylindrical rotating Rayleigh-Benard convection cell with radius-to-height ratio {Gamma} = 0.5. The Rayleigh number R is 2 x 10{sup 8}, the dimensionless rotation rate {Omega} varies from 10{sup 4} to 5 x 10{

A Multi-Relaxation-Time Lattice Boltzmann Method on Non- Uniform Grids for Large Eddy Simulation of Rayleigh-Bénard Convection Using Two Sub-Grid Scale Models

Journal of Applied Fluid Mechanics, 2014
In the present work, for the first time, the application of a Multi-Relaxation-Time Lattice Boltzmann (MRT-LB) model for large-eddy simulation (LES) of turbulent thermally driven flows on non-uniform grids is considered.

Conditional and unconditional nonlinear stability in fluid dynamics [PDF]

, 2002
In this thesis we examine some of the interesting aspects of stability for some convection problems. Specifically, the first part of the thesis deals with the Bénard problem for various Non-Newtonian fluids, whereas the second part develops a stability ...

Active control of Rayleigh-Benard convection

, 1996
Active feedback control strategies to alter the flow patterns in Rayleigh-Benard convection in a fluid layer heated from below and cooled from above were studied experimentally and theoretically. It was demonstrated that the transition from the no motion
