Domain

Chemical Reactor Design Toolbox Reference Manual

ChemReactorDesign.Basic.Liquid.Domain

Description

The liquid domain represents a mixture of \(N\) individual species with \(N \in \left[ 2 \, \dots \infty \right]\). Every species is characterized by an unique identifier.

The caloric properties of the pure species are calculated via lookup tables in terms of temperature as provided by the user.
