| 摘 要： | 在矩形翼的侧面粘贴一个小矩形辅翼,构成一种新型矩形翼纵向涡发生器,称为组合翼。在压力损失相等的条件下,通过实验比较了矩形通道内组合翼与原始矩形翼纵向涡发生器的流动与换热特性。结果表明:对于原始矩形翼,其最佳攻角为45°;与矩形翼相比,组合翼的换热明显增强,且阻力系数减小,尤其当辅翼布置在矩形翼的上游时换热增强与阻力系数减小效果更加明显;研究范围内,辅翼攻角为30°时的流动与传热综合效果最佳。

| Abstract: | With a small rectangular auxiliary wing being affixed at one side of the rectangular wing,called a combination wing,a new type of rectangular-wing longitudinal vortex generator is formed. Under the condition of the pressure loss being identical,the flow and heat exchange characteristics of the combination-wing longitudinal vortex generator and the original rectangular wing one in the rectangular passage were compared through experiments. The test results show that for the original rectangular wing,the optim... |
