Natural convection in an inclined enclosure
International Journal of Numerical Methods for Heat & Fluid Flow, 1997The 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, 1960The 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, 1982A 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

Natural convection in shallow water
Nonlinear Analysis: Real World Applications, 2007Starting from the 3D Boussinesq model and taking the limit as the domain thickness tends to zero, we derive rigorously the 2D model for natural convection in shallow water. The model reduces to a degenerated elliptic equation for the pressure, an explicit formula for horizontal components of the velocity and a vertical diffusion for the vertical ...

Natural Convection Film Boiling
2007If the wall temperature at film boiling is larger then the Leidenfrost or the socalled minimum film boiling temperature an unstable heat-transfer regime is observed, being partially film boiling and partially nucleate boiling called transition boiling.

This chapter introduces the notion of natural convection. In natural convection, the fluid velocity arises purely from the heating or cooling of the heat transfer surface itself. Heating creates less dense fluid next to the surface which tends to rise under buoyancy. Furthermore, the low velocities (compared to forced convection) give low heat transfer
