Investigation on the Flow behind a Circular Cylinder with a Wake Splitter Plate : 1st Report, Classification of Flow Patterns

Abstract

Experimental investigations were carried out on the flow characteristics around a circular cylinder with a wake splitter plate in the range of 1.3×10⁴≤Re≤5.8×10⁴. The gap between the cylinder and the platehaving O.29≤a/d≤1.76 long was varied. It is found that the effect of the length of the plate is divided into two types at a/d=1.O3 which have several remarkable flow patterns depending on the gap. Flow characteristics of those patterns were clarified.
