液幕状气液两相流流动特性的实验研究

提出了一种名为“液幕状气液两相流”的新流型。对液幕状气液两相流的流动特性进行了实验研究，着重研究液幕状气液两相流的床层高度和阻力特性以及气相和液相流动速度之间的关系，得到了当量床层高度、实际床层高度以及液幕床层阻力系数计算的关联式。这些关联式为液幕状气液两相流的研究提供了基础性的科学实验数据。

Experimental Investigation of the Flow Characteristics of a Gas-liquid Two-phase Flow Assuming the Form of a Gas-liquid Screen

A new flow pattern, the so-called "gas-liquid screen", is proposed and an experimental investigation of the gas-liquid two-phase flow characteristics based on this new flow pattern conducted. The investigation of the flow characteristics has been focused on the relationship between the above-mentioned bed layer height of the gas-liquid two-phase flow and resistance characteristics on the one hand and gas phase and liquid phase flow speed on the other. As a result, correlation equations for calculating equivalent bed layer height, actual bed layer height and the resistance factor of the gas-liquid screen bed layer were obtained. These correlation equations provide basic scientific test data for the research of the gas-liquid two-phase flow assuming the form of a gas-liquid screen.
