Stefan Tube

Application ID: 515

This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into air.
The concentration profiles are modeled at steady-state and validated against experimental data by Taylor and Krishna (1993).

This model example illustrates applications of this type that would nominally be built using the following products:
