It can now simulate multiphysics phenomena that require the coupling to the Heat Transfer in Porous Media and the Fluid and Matrix Properties features.This capability can be used to model non-isothermal flow in porous media, such as natural convection occurring due to a variable temperature distribution through a porous medium's matrix. In parallel, the Non-Isothermal Flow multiphysics coupling node, which is found in the Heat Transfer Module and CFD Module, has also been updated. This allows for the description of high interstitial velocities (i.e., high velocities in the pores).ДЄ Fluid and Matrix Properties feature has been introduced in the Single Phase Flow interface in COMSOL Multiphysics 5.1 in the following modules: Batteries and Fuel Cells, CFD, Chemical Reaction Engineering, Corrosion, Electrochemistry, Electrodeposition, Microfluidics, and Subsurface Flow. The Brinkman equations are solved in the porous domains and the Reynolds-averaged Navier-Stokes equations are solved in the free-flow domains.ДЇinally, your modeling capabilities have been extended by the fact that the Forchheimer term can be added to the equations for porous media flow. The Enable porous media domains checkbox adds the Fluid and Matrix Properties feature. You can either start with a porous media flow interface and add a free-flow domain or you can start with a free-flow interface and add a porous domain. These turbulence models are only available in the CFD and Heat Transfer Modules, but you can still couple them to Porous media flow interfaces available in other modules. You can activate this functionality by adding a Fluid and Matrix Properties domain node for the Algebraic yPlus or L-VEL turbulence models.

The Single-Phase Flow interfaces can now model turbulent flow in a free medium that is coupled to a porous medium.
