3. DESCRIPTION OF PROBLEM OR FUNCTION
COMPARE performs transient
calculation of the thermodynamic conditions in volumes connected
by flowing junctions with provision for mass and energy addition.
Volume thermodynamics and junction flows are for homogeneous
mixtures of: steam, two-phase water, any three perfect gases, or
combinations of the above. Critical vent flow is based on the
Moody equation. Subcritical flow is based on compressible orifice
flow of an ideal gas-like mixture with inlet and exit losses
resulting in a polytropic flow process. Flow with inertia is
calculated on the basis of an incompressible subelement
relationship. The program was written to perform transient
subcompartment analysis of nuclear power plants.
