摘要：
In order to study the particle characteristics of punching rectangular wing vortex generator, the diameter of 50nm Magnesium Oxide particles are used as the research object. The fouling and flow characteristics of the punching and non punching vortex generator were researched by comparative experiment, and the effect of the punch diameter, punch number and punch position on the particulate fouling characteristics were studied. The results show that in the same conditions, compared with non punching vortex generator, punching vortex generator has better inhibition scale and smaller loss of the flow resistance. With the increase of the diameter of punching vortex generator, asymptotic value of fouling resistance decrease, but the amplitude of decrease is reduced. The more number of punching holes, the smaller asymptotic value of fouling resistance, but they are not in proportion to the change. When the punching holes locate outside position of vortex generator, they can gain a better ability in restrain fouling. © 2016 Chin. Soc. for Elec. Eng.
