FLOW FIELD AROUND MULTIPLE CYLINDERS − A FLOW VISUALIZATION STUDY
摘要
In this study, the flow field around a combination of cylinders with a large cylinder (diameter D) at the center and four smaller cylinders (diameter d = D/2) placed symmetrically around the former is investigated using flow visualization. The gap between the large and smaller cylinders is systematically varied. At each gap results are obtained at various angles of attack. The results indicate that both the gap and the angle of attack have significant effect on the flow field. There can be strong periodic forces on the combination in certain situations and high local negative pressures can occur in other certain relative positions of the cylinder.
