Scaling Criteria for Two-Phase Flow Natural and Forced Convection Loop and Their Application to Conceptual 2 X 4 Simulation Loop Design.

摘要

Scaling criteria for a natural and forced convection circulation loop under single-phase and two-phase flow conditions are derived from the fluid balance equations, boundary conditions, and solid energy equations. For a single-phase flow case the continuity, integral momentum, and energy equations in one-dimensional area-averaged forms are used. For a two-phase flow case the one-dimensional drift-flux model obtained from the short time temporal averaging and the sectional area averaging is used.
