Abstract
A data bank of the mean and turbulent flow structure downstream from an impervious plate blockage in a square-pitch rod array spaced at a p/d ratio of 1.107 is described. The test section represented two interior interconnected subchannels and the plate blockage element fully blocked one subchannel. Measurements were made of the wall shear stress mean axial velocity distribution turbulence intensity Reynolds shear stress and turbulent kinetic energy at distances of 49.7 51.0 65.1 89.3 and 90.6 hydraulic diameters downstream of the blockage at an asymptotic unperturbed Reynolds number of 4.8 x 10 4.
