| 内容記述 | This paper reports on the experimental description of flow past two cylinders that stand side by side on an endwall. Flow visualization performed in a water tunnel provides a qualitative understanding of the three-dimensional flow over a range of control variables. Limiting streamline flow visualization shows the location of the three-dimensional separation for a range of cylinder spacings. For a spacing of 1.5 diameters between centers, the flow is described using a five-hole probe and by cylinder and endwall surface static pressure measurements. At a cylinder diameter Reynolds number of 250,000 the measurements show a single primary vortex with a wide flat cross section. The velocity measurements show high shear on the endwall in the primary vortex region. A small counterrotating vortex is found between the primary vortex and the cylinder leading edge. |
