Mass Transport PDEs and Boundary Conditions

Mass transport is a discipline of chemical engineering that is concerned with the movement of chemical species. The two mechanisms of mass transport are mass diffusion and mass convection. The driving force behind a mass diffusion is the difference in a species concentration at different locations. Mass convection, on the other hand, only occurs when species are transported in a moving fluid medium. The combination of these two mechanisms leads to changes in the species concentration field over time and is modeled with a mass balance equation.
