Abstract

Abstract: As an efficient heat and mass transfer technology,liquid film flow has been extensively used in chemical engineering and many other industries. In recent years,numerical simulation methods were widely applied in the study of the properties of the liquid film flow and heat transfer characteristics. This paper analyzed the liquid film free surface tracking methods of numerical simulation. Four aspects,including different wall structure,different wall angle,liquid property,liquid flow rate and gas velocity were summarized. The features of fluctuations were investigated through changing the wall angle,the inlet Reynolds number and inlet disturbance. In addition,the research status of heat and mass transfer characteristics were summarized. The disadvantages of using numerical simulation method to study liquid film flow were also discussed. The more scientific and reasonable methods of researching the liquid film flow were prospected.

Key words: liquid film, flow dynamic, surface waves, heat and mass transfer, numerical simulation

摘要： 液膜流动现象广泛存在于自然界中,作为一种高效传热传质技术,其在化工等领域有着广泛的应用。近几年来,国内外学者越来越热衷于运用数值模拟技术来研究液膜的流动特性及传热传质特性。本文归纳分析了数值模拟研究中液膜自由液面的追踪方法。总结了不同壁面结构、不同壁面倾角、液体物性、液相流量与气相流速4个方面对液膜的流动特性的影响规律,以及改变壁面倾角、入口雷诺数、入口添加扰动时表面波呈现的波动特性。此外,还论述了流动液膜的传热传质特性的研究现状。所得结论对流动液膜的数值模拟研究具有一定的参考价值,最后提出了用数值模拟方法研究液膜流动的缺陷与不足,展望了更加科学合理地研究流动液膜的方法。
