Rayleigh-Bénard convection: bounds on the Nusselt number

open access: yes, 2016
We examine the Rayleigh–Bénard convection as modelled by the Boussinesq equation. Our aim is at deriving bounds for the heat enhancement factor in the vertical direction, the Nusselt number, which reproduce physical scalings. In the first part of the dissertation, we examine the the simpler model when the acceleration of the fluid is neglected (Pr ...

A study of Nusselt number distributions in a curved channel.

open access: yes, 1992
The effects of curvature and the resulting centrifugal instabilities on local heat transfer distributions are studied in a curved channel with a rectangular cross section and a 40 to 1 aspect ratio at Dean numbers from 100 to 278. The experimental conditions are identified for which forced convection with weak buoyancy, and forced convection with ...
