摘要

气液两相流中界面波的存在对传热、传质、阻力特性及稳定性都有很大影响。前人有关界面波的研究大多偏重于两相流中界面波的类型及其转变

而对其特征参数变化规律(如振幅、波长、频率和速度等)的研究则很少。但界面波对气液两相流流动阻力和流动结构影响机理的深入研究必须以了解界面波的各特性参数为前提

同时界面波有关特性参数的深入研究也可为气液两相流的数学理论化提供实验基础。本文以气、水为工质

系统研究了水平矩形管内气液两相流的界面波特性。根据界面波在时域、幅域内的不同特征区别出了各种类型的波并给出了相应的波形和流型图。着重研究了界面波各特征量随气液两相流量变化的变化规律。

Abstract

With air and water as the working fluids

an experimental study on the characteristics of the interfacial waves in gas - liquid two - phase flow in a horizontal rectangular channel was conducted by using three two - parallel conductance probes to measure the instantaneous liquid film thickness. The test section was entirely made of plexiglass plate and the length is 6690mm long. Its cross section was 150mm×25mm. In this experiment the maximum gas superficial velocity was 14.6m·s-1 and the water superficial velocity 0.110m·s-1. The wave pattern and flow pattern of gas - liquid two- phase flow were distinguished and defined

and compared with the results of previous studies. Furthermore

the characteristics of interfacial waves

such as wave speed

wavelength

wave frequency and wave amplitude were investigated in terms of the gas and liquid volumetric fluxes.
