Visualizing complex thermodynamic relationships in multidimensional space
is helpful for the prediction and control of multi-component, multi-phase systems.
This facility is of critical importance for particle technology.
The basis for and examples of such visualizations are presented on
the Gibbs Model Website by Prof. Ken Jolls (Iowa State Univ.)
and Dr. Daniel Coy (Nanophase Technologies Corp.)
See
www.public.iastate.edu/~jolls/
Two-dimensional displays of multi-phase thermodynamic diagrams
are produced by "Phase", a computer program developed by Jolls and Coy
and made portable by Prof. Walter G. Chapman's group (Rice Univ.).
You may obtain a copy of this program from

Abbreviations
CFM = Computational Fluid Mechanics:
the system is treated as a set of cells whose internal properties are treated
as homogeneous. If the system is symmetric, calculations for a few cells may
be used to simulate the whole system.
DEM = Discrete Element Modelling:
the position of each particle is tracked separately.
FEM = Finite Element Modelling:
parameters representing constitutive properties are used to treat
the system as a continuum.
TFM = Two-Fluid Modelling:
the particle cloud is treated as a second fluid phase within the suspending fluid
