|
|
A class for chemically-reacting solutions.
|
|
|
|
Instances can be created to represent any type of solution -- a
|
|
mixture of gases, a liquid solution, or a solid solution, for
|
|
example.
|
|
|
|
Class Solution derives from classes ThermoPhase, Kinetics, and
|
|
Transport. It defines very few methods of its own, and is
|
|
provided largely for convenience, so that a single object can be
|
|
used to compute thermodynamic, kinetic, and transport properties
|
|
of a solution. Functions like IdealGasMix and others defined in
|
|
module gases return objects of class Solution.
