Two-Phase Flow Studies: Part I

Group II report, ICI Central Instrument Research Lab

Summary
Results of experiments on two-phase systems composed of silicone oil and air, and water and air, are presented. The silicone oil-air system is designed to simulate conditions in the continuous nylon polymeriser (ICI Fibres), while the water-air system is designed to simulate conditions in the adipic tubular vaporiser (Dyestuffs Division). The values of the experimental variables which enable an accurate dynamical simulation of each system to be made were established by analysis in previous reports.
The individual experiments were designed principally to confirm or modify the validity of standard predictions for pressure-drop, hold-up, and flow regime, under conditions for which reliable data was not available. In addition the experimental results were employed to test the validity of a simple relationship between pressure-drop and hold-up which has been derived in the course of the study.
