Flow Visualization on Gas-Liquid Two-Phase Flow with Contraction

Journal of the Visualization Society of Japan, 2007
This paper described about flow visualization of a gas-liquid two-phase flow in vertical channel with contraction. We have found that the pulsation for void fraction and pressure are occurred by the contraction. However, the mechanism of pulsation is not cleared.

Modelling and Basic Equations of Gas-Liquid Two-Phase Flow

JAPANESE JOURNAL OF MULTIPHASE FLOW, 1990
A review is made of the various models and basic equations of gas-liquid two-phase flows which are indispensable for accurate analyses of the phenomena. As the most detailed model, a local instantaneous representation of mass, momentum and energy conservation is shown. Then, averaging procedures for the various physical quantities and their derivatives
