Details the reactions that take place between a fluid film phase and a neighbouring gas phase.

[reaction]

For fluid film interphase reactions, the defined reaction Type can only be Interphase.

Reactants: Reactant components of the reaction at the interphase between the fluid film and the gas phase.

Products: Product components of the reaction at the interphase between the fluid film and the gas phase.

Properties: Reaction rate for the reaction at the interphase between the fluid film and the gas phase Eqn. (3587).

Reaction Coefficient: Specifies the reaction coefficient $k_{i}$ for the reaction rate Eqn. (3587). For reactions at the interphase between the fluid film and gas phase, only a user-defined reaction coefficient is available.

Interphase Transfer Species Source of [reaction component] of [phase interaction]: Refers to the net source term $S_{Y_{i}}$ for species $Y_{i}$ due to the interphase reactions.; See equations Eqn. (3351) and Eqn. (3352).
Interphase Transfer Species Source Jacobian of [reaction component] of [phase interaction]: Refers to the net Jacobian of the source term $S_{Y_{i}}$ for species $Y_{i}$ , defined as $\frac{ⅆ S_{Y_{i}}}{ⅆ Y_{i}}$ , which represents the derivative of source term $S_{Y_{i}}$ with respect to the mass fraction of species $Y_{i}$ .
