Experimental study on drag reduction characteristics of bionic jet surface
摘要
Abstract
Based on the theoretical analysis of bionic jet surface offish gill slits, the drag reduction characteristics of revolution of bionic jet surface were studied by jet experiment. The friction torques of smooth surface experiment model and jet surface experimental models at different rotation speeds were tested by using torque signal coupler, and then the jet friction reduction characteristic curve was obtained. The results show that the bionic jet surface has remarkable drag reduction effect, and the friction reduction rate has a close relation with the speed, the jet velocity and the jet aperture of the experimental model. The maximum friction reduction rate can be 10.8%.关键词
