Regime-4 Code for Prediction of Flow Regime Transition in a Horizontal Pipe, Annulus and Bundle Flow Under Gas-Liquid Two-Phase Flow

Abstract

REGIME-4 code for prediction of flow regime transition in a horizontal pipe, annulus and bundle geometries under cocurrent gas-liquid two-phase flow has been developed, and an experimental confirmation has been conducted. The results show that the present code predicts relatively well all flow regime transitions for these geometries.
