The Reacting Turbulent Flow, k-ε, Diluted Species Interface
This multiphysics interface e () is used to simulate flow in the turbulent regime coupled to transport of dilute solutes present in a gas or liquid.
It combines the Turbulent Flow, k-ε and Transport of Diluted Species interfaces. The Reacting Flow, Diluted Species multiphysics coupling, which is added automatically, couples the fluid flow and mass transport and applies turbulence modeling for the mass transport. 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 Turbulent Flow, k-ε interface are the Navier-Stokes equations for conservation of momentum and the continuity equation for conservation of mass. Turbulence effects are modeled using the standard two-equation k-ε model with realizability constraints. Flow close to walls is modeled using wall functions.
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. Mass transport close to solid walls is modeled using wall functions.
