A Porous Media Transport Properties feature has been added the Transport of Concentrated Species interface. This feature includes models for computing effective transport properties dependent on the porosity of the material and can be used to study species transport in a fluid mixture propagating through a porous medium.
A new Reaction feature is available in the Transport of Concentrated Species interface. It defines species source terms from a single chemical reaction, using an Arrhenius or user-defined rate expression. When licensed to the CFD Module, the feature includes the possibility to model the turbulent reaction rate using the eddy-dissipation model.
The Reaction Sources feature corresponds to the previous
Reactions feature in the Transport of Concentrated Species interface and the concentrated species version of the Reacting Flow in Porous Media interface. The feature in Transport of Concentrated Species has also been extended with a
Reacting Volume section, which can be used to specify the basis for the reaction source terms on porous media domains.
Surface species functionality has been added to the Reactive Pellet Bed feature (in the Transport of Diluted Species interface and the Transport of Diluted Species in Porous Media interface). Surface species existing within the porous pellet, attached to the solid matrix-fluid interface, can be defined in the
Surface Species section of the feature. Adding surface species, the
Reactions subfeature includes the possibility to model surface reactions and corresponding heat sources.
Surface reactions, defined in the Reaction Engineering interface, can now be exported to occur within porous pellets in a space-dependent model, using the Generate Space-Dependent Model feature. Selecting to export surface reactions to porous pellets, a
Reactive Pellet Bed feature is added (in a Transport of Diluted Species interface or Transport of Diluted Species in Porous Media interface) and automatically set up to include the defined reaction kinetics.
