Statistics and Scaling in Turbulent Rayleigh-Bénard Convection

In fluid thermodynamics, Rayleigh–Bénard convection is a type of natural convection, occurring in a planar horizontal layer of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells. Bénard–Rayleigh convection is one of the most commonly studied convection phenomena because of its analytical and experimental accessibility. The convection patterns are the most carefully examined example of self-organizing nonlinear … WebDec 6, 1999 · The subgrid scale estimation model, which has been previously studied for large eddy simulations of turbulent channel flow, was extended to convective flows.
