On the Problem of Natural Convection

1991
The problem of natural convection in a horizontal layer of viscous thermally conducting fluid heated from below (Benard problem) is relevant in many physical situations and, in particular, in geophysics and astrophysics. Our goal is to give an account of the questions arising in the determination of the critical value that the Rayleigh number must ...

Natural convection in an inclined enclosure

International Journal of Numerical Methods for Heat & Fluid Flow, 1997
The effect of inclination on laminar natural convection in a square cavity is studied numerically for inclination angles ranging from 40° to 160°, Rayleigh numbers between 103 and 106 and Prandtl numbers from 0.02 to 4,000. Contours of stream functions and temperature are presented in order to provide a new insight and a better understanding of the ...

Natural convection above fires

Journal of Fluid Mechanics, 1960
The turbulent natural convection above fires in a dry calm atmosphere with a constant lapse rate has been the subject of several recent investigation (see references). The present paper presents solution curves from which the natural convection may be computed over a fire of arbitrary size in an atmosphere with arbitrary lapse-rate variation.

Natural Convection Driven by Osmosis

SIAM Journal on Applied Mathematics, 1982
A semi-permeable membrane forms part of a vertical plane boundary which separates pure solvent from a solution of bulk concentration $C_b $. The osmotic flux J is given by $J = P\Delta C$ where P is the osmotic permeability of the membrane and $\Delta C$ is the concentration difference across it, less than $C_b $ because the osmotic flow tends to sweep
