% MIXTURE - Multiphase mixtures.
|
|
%
|
|
% Class Mixture represents
|
|
% mixtures of one or more phases of matter. To construct a mixture,
|
|
% supply a cell array of phases and mole numbers:
|
|
%
|
|
% >> gas = importPhase('gas.cti');
|
|
% >> graphite = importPhase('graphite.cti');
|
|
% >> mix = Mixture({gas, 1.0; graphite, 0.1});
|
|
%
|
|
% Phases may also be added later using the addPhase method:
|
|
%
|
|
% >> water = importPhase('water.cti');
|
|
% >> addPhase(mix, water, 3.0);
|
|
%
|
|
% Note that the objects representing each phase compute only the
|
|
% intensive state of the phase -- they do not store any information
|
|
% on the amount of this phase. Mixture objects, on the other hand,
|
|
% represent the full extensive state.
|
|
%
|
|
% Mixture objects are 'lightweight' in the sense that they do not
|
|
% store parameters needed to compute thermodynamic or kinetic
|
|
% properties of the phases. These are contained in the
|
|
% ('heavyweight') phase objects. Multiple mixture objects may be
|
|
% constructed using the same set of phase objects. Each one stores
|
|
% its own state information locally, and synchronizes the phase
|
|
% objects whenever it requires phase properties.
