波形竖管降膜蒸发流动与传热性能的理论研究

本文简介波形竖管降膜蒸发流动与传热的过程,通过理论分析建立波形竖管降膜蒸发传热的数学模型。采用国外一些研究者得到的理论分析与实验结果,利用无穷泰勒级数将含有多重积分的数学模型展开,得到简单实用的半经验——半理论数学模型解析式。

Theoretical Study on Characteristics of Falling Film Evaporation Hydrodynamics and Heat Transfer in a Vertical Wavy Wall Tube

This paper described the hydrodynamics and heat transfer process of falling film evaporation in a vertical wavy wall tube, mathematical model of heat transfer is theorized. Using theoretical analysis and experimental results from foreign researchers, a mathematic model of multiple integral was expanded with infinite Taylor series to get a simple and practical analytic equation with half-experience and half-theory.
