Title: Theoretical basis for two-phase disengagement and vapor fraction calculations

Abstract

This paper reviews the theoretical basis for disengagement calculations. That is the assumptions of pseudo-steady-state, volumetric gas production and applicable drift-flux correlations. Using these an axial void fraction profile can be calculated. The use of graphical, analytical, and simplified-equation-based correlations for vertical cylinders, horizontal cylinders, and spheres are covered. Before disengagement occurs the vent stream void fraction can be estimated using the coupling equation. The implications of the converging cross-sectional area of horizontal cylinders and spheres are discussed for both disengagement and two-phase flow calculations. 22 refs., 9 figs., 5 tabs.
