Özet

Using an experimental approach, flow around a blunt-based flat plate of thickness H and a downstream circular cylinder of diameter D = 0.75H in tandem and staggered arrangements have been investigated at Reynolds numbers of Re-l= 1.46 x 10(5), 2.72 x 10(5) and 3.71 X 10(5) based on the plate length l. The investigation focuses on the effect of a wide range of values of longitudinal and transverse spacing between the plate and the cylinder on the mean pressure distributions around the base of the plate and the cylinder as well as the drag and lift coefficients of the cylinder. For both the tandem and the staggered arrangements the mean pressure distributions indicate the existence of a critical spacing on either side of which different flow interferences take place.
