摘要

使用激光多普勒风速仪测量了圆柱管中垂直上升的两相液滴流动的速度曲线和体积浓度，在这种流动中，两相之间的密度差相对较小。这种情况模拟了微重力条件下气液两相混合物的流动。小相滑移速度是通过实验测得的。开发了使用激光多普勒风速仪测量分散两相流中各相速度和体积浓度的新方法。

Laser Doppler Anemometry of a Dispersed Mixture of Two Liquids with Similar Densities

The velocity profiles and volumetric concentrations were measured using a laser doppler anemometer for a vertically ascending two-phase liquid–liquid droplet flow in a cylindrical tube, where the density difference between the phases is relatively small. This regime simulates the flow of a two-phase gas–liquid mixture in microgravity. The small phase slip velocity was experimentally measured. New methods have been developed for using a laser doppler anemometer to measure the velocity and volumetric concentration of phases in a dispersed two-phase flow.
