#include <liquidMixture/liquidMixture.H>
A mixture of liquids.
The theory in this class is to a very large extent based on the book: 'The Properties of Gases & Liquids' 4th ed. by Reid, Prausnitz and Poling
For now it does not do much, since the perfect gas equation is used.
The dictionary constructor searches for the entry liquidComponents, which is a wordList. The liquid properties of each component can either be contained within a liquidProperties sub-dictionary or (for legacy purposes) can be found directly in the dictionary. The liquidProperties sub-dictionary entry should be used when possible to avoid conflicts with identically named gas-phase entries.
A simple example of a single-component liquidMixture:
