|
|
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 :class:`.ThermoPhase`, :class:`.Kinetics`,
|
|
and :class:`.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 :func:`.IdealGasMix` and others defined in
|
|
module gases return objects of class :class:`.Solution`.
