Reaction Sources
This subnode is available to the Gas Phase nodes when the Advanced Physics Options is selected in the Show More Options dialog shown when the Show More Options button () is selected, in combination with the Include gas phase diffusion or Use Darcy’s law for momentum transport checkbox being selected in the interface top node for the corresponding gas mixture.
The node may be used for adding additional mass sources in a model, typical stemming from nonfaradaic reactions such as water condensation-evaporation or water drag in a low-temperature fuel cell, or homogeneous reactions such as the water gas shift reaction in a molten carbonate fuel cell. The node contains text fields for specifying the mass or molar reaction sources of all active gas phase species, including liquid water.
The Heat Source is calculated automatically when the Built in option is used.
The default selection is all domains of the parent node, but may be changed.
