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. %8 2010-04-01
