摘要:
为了提高翅片式换热器的强化传热性能,对不同攻角的纵向涡发生器的翅片区域进行了研究. 采用流体仿真软件FLUENT对发生器的翅片区域建立六面体网格模型,对不同攻角的纵向涡发生器的努塞尔数、阻力因子、综合性能分别进行数值分析和对比. 结果显示:随着纵向涡发生器的攻角增加,纵向涡翅片的努塞尔数增强的越来越明显,其中纵向涡发生器攻角为45°的翅片努塞尔数最大;同时随着纵向涡发生器的攻角增加,阻力因子也随之增加;带纵向涡发生器的翅片的传热效果强于不带纵向涡发生器的翅片;通过比较综合评价因子,攻角为45°的纵向涡翅片在雷诺数为2000~6000内,综合性能最好.
Abstract:
To improve the heat transfer performance of fin heat exchanger, the fin areas of longitudinal vortex generator with different attack angles were studied. Hexahedral mesh model of fin area of longitudinal vortex generator was established by fluid simulation software FLUENT, Nusselt number, Resistance Factor and comprehensive performance of longitudinal vortex generator with different attack angles were numerically analyzed and compared. The results show that the Nusselt number of longitudinal vortex fin increases with the attack angles of longitudinal vortex generator increasing, and it is biggest at 45° attack angle; the friction factor increases with the attack angles of longitudinal vortex generators increasing; the heat transfer effect of fin with longitudinal vortex generator is better than that without longitudinal vortex generator; the comprehensive performance of longitudinal vortex fins is best when the attack angle is 45° in 2000-6000 Reynolds number.
