massatotransport
Massatotransport is a term sometimes used to describe the collective movement of mass within and between phases, driven by gradients in concentration, temperature, pressure, or electric potential. In practice, it overlaps with the broader field of mass transfer or mass transport phenomena, and its exact usage can vary by discipline. The central idea is to understand how species move and distribute themselves in space and over time.
The fundamental mechanisms include diffusion, convection (advective transport), dispersion, and, in charged systems, electromigration. In simple
In porous media and environmental contexts, massatotransport models often combine advection, dispersion, and diffusion to predict
Terminology varies, and some texts reserve the terms mass transfer or mass transport for these concepts. Massatotransport
