摘要

为了探究开孔涡流发生器颗粒污垢机制，实验研究了腰槽开孔矩形翼涡流发生器纳米氧化镁颗粒的污垢特性，考察了入口温度、浓度、流速、涡流发生器纵向间距以及不同攻角等参数污垢特性的影响。结果表明：腰槽开孔矩形翼涡流发生器具有较好的抑垢特性，抑垢能力随入口温度降低、浓度降低、流速增加以及纵向间距减小而增强。涡流发生器60°攻角布置下的抑垢能力最强。

Abstract

In order to explore fouling mechanism of nanoparticles in hole-punched vortex generator

magnesia nanoparticles were used experimentally in rectangular wing vortex generator with hole-punched at waist groove

which factors of inlet temperature

concentration

flow velocity

longitudinal space and attacking angle of vortex generator were studied. The experimental results showed good anti-fouling performance of the waist-groove-punched rectangular wing vortex generator and its significant dependence on operating conditions. High flow velocity

low magnesia particle concentration

low inlet temperature and short longitudinal space could enhance anti-fouling capability. The best anti-fouling was at the attacking angle of 60°.
