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。

关 键 词:腰槽开孔矩形翼涡流发生器  氧化镁  污垢特性

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°.
Keywords:waist groove punched rectangular wing vortex generator  magnesia  fouling characteristics
