摘要
利用电子探针传感器在不施加探针电压情况下,仍可测出气液两相流中的液滴粒度及其分布,这是由于气液两相物质的喷射流动作用造成液滴带电所致。如能得知液滴尺寸与其带电量的关系,对于液滴粒度及其分布的测量是十分重要的。本文提出一种液滴尺寸与其带电量的关系及其测试方法。
The electronic probe sensor can be used to measure the size-distribution of liquid droplets in gas-liquid two-phase flow, for the probe's voltage U=0. The principle is that, the droplets is charged several quantity of electrons by the jet flow of gas and liquid. It is important that is measured the liquid droplet size distribution, if the relation of size and charges is known. This paper describes a relation of the liquid droplet size and its charges, and its measuring method.
