Building a reduced model for nonlinear dynamics in Rayleigh-Bénard convection with counter-rotating disks.

Abstract

A reduced model to decrease the number of degrees of freedom of the discretized Navier-Stokes equations to a small set that nevertheless captures the essential dynamics of the flow is proposed. The Rayleigh-Bénard convection problem in a cylinder of aspect ratio one where the lower and upper disks, maintained at hot and cold temperatures, respectively… (More)
