摘要 在矩形翼的基础上,提出一种新型的八边形翼纵向涡发生器.在矩形通道内,通过试验比较了矩形翼和八边形翼纵向涡发生器的流动与传热特性.分别在Re相同和阻力损失相同的条件下,分析了不同纵向涡发生器的强化传热效果.结果表明:与矩形翼相比,八边形翼纵向涡发生器的强化传热效果更好,而阻力系数没有明显增加;在阻力损失相同的条件下,矩形翼和八边形翼纵向涡发生器的传热增强率小于在Re相同时的传热增强率. A novel longitudinal vortex generator（LVG） with octagonal wings is being presented based on conventional LVGs with rectangular wings.Flow and heat transfer characteristics in the rectangular channel with LVGs respectively using rectangular or octagonal wings were experimentally studied and compared,while heat transfer enhancement effects of different LVGs analyzed under same Re and pressure drop conditions.Results show that compared with LVG with rectangular wings,the LVG with octagonal wings has better heat transfer effects,and its drag coefficient does not increase obviously.Heat transfer enhancement of LVGs with rectangular or octagonal wings under same pressure drop conditions is weaker than that under same Re conditions.
