Modeling Interphase Reactions
Mass transfer can be modeled as a reaction between two multi-component Eulerian phases, usually one liquid and one gas phase.
The steps in this procedure are intended to follow on from Step 5 in Modeling Bubbly and Droplet Flows.
To model interphase reactions:
-
For the physics continuum that represents the Eulerian multiphase flow, select
the following model in addition to the models that you previously selected.
Group Box Model Optional Models Phase Coupled Fluid Energy -
In the phase interaction, select the following models in addition to the
models that you previously selected:
Group Box Model Energy

- Segregated Fluid Enthalpy
- Segregated Fluid Temperature

Define the reactions that occur between the phase components.
-
Right-click the
node and select
New Reaction.
A new reaction definition is added.
- For each component that you want to include in the reaction, right-click the node, click Add Reactant, and then select the component.
- For each product of the reaction, right-click the node, click Add Product, and then select the product.
-
For each reaction component and product, select the component node and, in the
Properties window, specify the appropriate values:
Stoich. Coeff. The stoichiometric coefficient that is appropriate to the reaction. Rate Exponent The rate exponent that is appropriate to the reaction. - Select the node and specify the appropriate reaction rate properties.
