Domain

Chemical Reactor Design Toolbox Reference Manual

ChemReactorDesign.Basic.Solid.Domain

Description

The solid domain represents a pseudo fluidic 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.
