摘要

在降膜塔流体力学试验中

利用激光透过液膜时产生丁铎尔现象来测量降膜管内液膜厚度随时间的变化

本文叙述了测量仪器的原理和结构并提出校验结果.

Abstract

In the hydrodynamics experiments of a falling-film column

the change of the thickness of fluid film in the falling-film tube with time has been measured

using the Tyndall effect produced by a Laser beam passing through the fluid film. The principle of the test instrument and its construction are described and the results of calibration are presented.
