并列双圆柱绕流中宽窄尾流的识别方法
A method for distinguishing WW and NW in the flow around two side by side circular cylinders
摘要
Abstract
A pure-Lagrangian vortex method, based on Instantaneous Vorticity Conserved Boundary Condi⁃tions (IVCBC), is adopted to build the numerical calculation model of flow around double circular cylinders that have the same structure characteristics of two side by side circular cylinders. The Wide Wake(WW) and Narrow Wake(NW)appear in the range of pitch ratio T/D=1.1~2.6. A scheme is proposed to distin⁃guish the NW and WW through the direction synchronism between induced velocity at the middle of double circular cylinders and deflection of gap flow. By comparing the directions of the above two flowing condi⁃tions and analyzing the classic case, it is concluded that the proposed method could distinguish WW and NW accurately, which offers an important numerical calculation method for investigating the flow character⁃istics in this range.关键词
