The Reacting Laminar Flow, Diluted Species Interface
The Reacting Laminar Flow, Diluted Species multiphysics interface () is used to simulate laminar flow coupled to transport of dilute solutes in a gas or liquid.
It combines the Laminar Flow, and Transport of Diluted Species interfaces. The Reacting Flow, Diluted Species multiphysics coupling, which is added automatically, couples fluid flow and mass transport. The fluid flow can either be free flow or flow in a porous medium. The mass transfer solves for the development of one or several solutes dissolved in a gas or liquid solvent.
The interface can be used for stationary and time-dependent analysis in 2D, 2D axial symmetry, and 3D.
On the constituent physics interfaces:
The equations solved by the Laminar Flow interface are the Navier–Stokes equations for conservation of momentum and the continuity equation for conservation of mass. A Fluid Properties feature is active by default on the entire interface selection. A Porous Medium feature can be added in order to model flow in porous media by solving the Brinkman equations.
The Transport of Diluted Species interface solves for an arbitrary number of concentrations. The species equations include transport by convection, diffusion and, optionally, migration in an electric field.
