纵向涡发生器强化传热的研究历程及进展

The development process and perspective of heat transfer by longitudinal vortex generators

首先简要回顾了纵向涡发生器的发展历程,对前人进行的关于纵向涡发生器的实验研究和数值分析进行了归纳分析,并运用场协同原理对纵向涡强化换热的机理进行了初步分析。最终得出结论,对以后纵向涡发生器的发展和研究给出具体意见,认为系统地了解纵向涡发生器各种各样的几何参数对换热和压降的影响,对于将纵向涡发生器成功地用于紧凑式换热器是非常重要的。

A brief review on research progress of longitudinal vortex generators（LVG） was given in the first.Based on the summarization and analysis of the past experimental research and numerical analysis on LVGs,a primart explanation on the mechanism of heat transfer enhanced by LVGs was presented by using the Field Synergy Principle.Concrete suggestions were put forward about the direction of the development and research work of LVGs in the end.Systematic understanding of the effect on heat transfer and pressure drop caused by various geometry sizes of LVGs is an important basis for making successfully use of LVGs in compact heat exchanger.
