Introduction
Convection is ubiquitous in nature and plays an important role in numerous engineering and earth science problems. It occurs as pore fluid moves within the soil. The movement of the fluid can be generated by external forces (such as pressure), or then again, by the forces of gravity acting on fluid density variations. These fluid density variations may result from non-uniform temperature fields and/or non-uniform concentration of any of the fluid components. In the presence of a nonuniform temperature field, most fluids become lighter and rise when heated, and become denser and fall when cooled. These movements inevitably alter the thermal regime, affect the fluid density, and create a coupled system. The manner in which this buoyancy-driven flow occurs depends on the boundary conditions and the geometry (or shape) of the domain. The objective of this example is to verify the heat and mass transfer formulation against a widely used benchmark for natural convection of pure water in a porous cube. In this problem, the cubic enclosure is heated from below and cooled from the top while the vertical walls are considered impervious and rigid barriers to heat transfer. The exercise lends credibility to the use of the software for multi-dimensional problems involving natural convection.
