COMMIX-2: a three-dimensional transient computer program for thermal-hydraulic analysis of two-phase flows
Creators
Description
The mathematical bases of the computer program COMMIX-2 are described in detail. COMMIX-2, which describes steady-state and transient single and two-phase flow conditions, has been developed from the single-phase flow version of COMMIX, COMMIX-1A, and relies on the same concepts of volume porosity, directional surface porosity, distributed resistance, and heat source. Two models for two-phase flow are included in the program: one is a three-equation Slip Model (SM), which assumes either a constant slip ratio between the phase velocities, or a relative slip velocity normalized by the mixture velocity; the other is a five-equation unequal phase velocity, equal phase temperature (UVET) model, which is referred to as the Separated Phases Model (SPM). This report documents the state of the program development as of October 1984. 12 refs
