摘要
本文基于气液两相分相流模型和动量守恒原理，并结合若干假定，建立了气液两相并流流动体系的气含率一般表达式，给出了由测定压降利用该表达式在确定管内气液垂直向下并流体系气含率中的应用。验证表明，Ｈｉｌ提出的气液两相垂直向上并流流动体系的气含率表达式为本文建立一般公式当θ＝９０°时的特例。
A general expression for gas holdup in gas-liquid two phase cocurrennt flow systems was derived from two phase separated flow model, based on momentum conservation principle, in combination with assumptions on this kind of flows. Applied example was presenled on gas holdup in verlical downward gas-liquid two phase flow systems determied from observed pressure drop by using the present expression. Hill's gas holdup expression for vertical upward gas-liquid flow is simply the specific case for the general expression with θ=90° in the persent work.
