Multi-Phase Macrotransport Processes
[ Home ] [ Overview ]
The subject of macrotransport processes encompasses a broad range of macroscale volume-averaged transport phenomena in continuum-based descriptions of multiple-phase multiple-species geosystems subjected to prescribed boundary and initial conditions. Problems previously addressed and currently being investigated within the scope of the Granular Lab cover the following fields of study: heat and mass transfer in heterogeneous multi-phase porous media; advective-diffusive-reactive transport phenomena in capillary networks arising in granular systems (such as in packed-beds); and, contaminant dispersion in natural water systems. The primary application is resolution of multidimensional multi-phase multi-species macrotransport processes in multiplicity of time and space (i.e., multiple scales). Thus, the scale-dependency of rate-controlling physicochemical processes is considered in the detailed solution of pertinent partial differential equations governing macrotransport phenomena in the particular systems subjected to specified boundary and initial conditions.
