本文从综述两相管流的动力学出发,对两相管流中低固——气比的气——固系统和双成分气——液系统的测量问题提出了一些可能的方法,主要结论是:1.目前文献中提出的测量方法一般都未考虑两相管流动力学特性,因而结论不正确,在研究两相管流流量测量问题时必须从两相管流的特性出发;2.对于气——固系统的流量测量,关键在于找出固体粒子筛分分布与有效粒径之间的关系;3.对于气——液系统,指出流型是一个重要的因素,必须首先判定流型,才能从测得的数据中较正确地判定流量。
Based on the review of the dynamics of two-phase pipe flow, some possible methods are proposed for the measurement of low solid-gas ratio gas-solid system and two-component gas-liquid system in two-phase pipe flow. The main conclusions Is: 1. The measurement methods proposed in the literature generally do not consider the dynamic characteristics of the two-phase pipe flow, and thus the conclusion is not correct, in the study of two-phase pipe flow measurement problems must be based on the characteristics of two-phase pipe flow; 2. For Gas-solid system flow measurement, the key lies in finding out the relationship between the solid particle size distribution and the effective particle size; 3. For the gas-liquid system, pointed out that the flow pattern is an important factor, we must first determine the flow pattern , In order to be able to judge the data correctly from the measured traffic.
