Domain

Chemical Reactor Design Toolbox Reference Manual

ChemReactorDesign.Basic.Interface.Domain

Description

The interface domain represents a pseudo-fluidic ¹ mixture of $N$ individual species with $N \in \left[ 2 \, \dots \infty \right]$ living on an Langmuir ² surface. Every species has a characteristic specific area.

The domain is modelled as isothermic, i.e. no heat balance is accounted for.
