TLDR
In this article, the problem of free and natural convection with combined driving forces is considered in general and all possible configurations are identified, and dimensionless parameters are discussed in order to help categorize the various problems.Abstract:
The problem of free and natural convection with combined driving forces is considered in general and all possible configurations are identified. Dimensionless parameters are discussed in order to help categorize the various problems, and existing work is critically evaluated. Four distinct cases are considered for conventional convection and for the situation when the body force and the density gradient are parallel but opposed. Considerable emphasis is given to unstable convection in horizontal layers.read more

Heat and mass transfer by natural convection in a porous medium
Adrian Bejan,Khairy R. Khair +1 more
TL;DR: In this paper, the authors reported a fundamental study of the phenomenon of natural convection heat and mass transfer near a vertical surface embedded in a fluid-saturated porous medium, which is due to the variation of temperature and concentration across the boundary layer.

A continuum model for momentum, heat and species transport in binary solid-liquid phase change systems. II: Application to solidification in a rectangular cavity
W.D. Bennon,Frank P. Incropera +1 more
TL;DR: In this article, a newly developed continuum model has been used with a well-established control-volume-based, finite-difference scheme to investigate solidification of a binary, aqueous ammonium chloride solution in a rectangular cavity.

Natural convection with combined heat and mass transfer buoyancy effects in a porous medium
TL;DR: In this paper, a comprehensive study of the natural convection phenomenon occurring inside a porous layer with both heat and mass transfer from the side is described, which is driven by a combination of buoyancy effects due to both temperature and concentration variations.
