圆柱绕流的流动分离控制
A flow separation control on cylinder flow
摘要
Abstract
Flow separation observed in surface-piercing cylinder flow is a major cause of unexpected drag increase in marine structures. Experimental study and CFD analysis of a hydrodynamic flow separation control through vortex generators (VGs) were conducted in Shanghai Jiao Tong University. Vortex generators have been widely used in the aircraft industry to prevent or delay flow separation over wings. The function of VGs is to introduce vortices into the flow ahead of the separation point to energize the boundary layer on the bottom and thus to delay the flow separation. The towing test results of a surface-piercing cylinder flow demonstrate the VG's effectiveness for resistance reduction in marine structures.关键词
