Abstract
The fluidic behaviors and interactions present in a setup utilizing perforated blockages and downstream pin-fin are elucidated: specifically, the role of jet curvature in flow interactions and the interaction of end-wall flows around the pin-fins subjected to impinging jet. To this end, a combination of particle image velocimetry-based measurements and oil-dye surface flow visualization technique is utilized. Two different configurations of jet flows, with or without flanking jets, and three different distances between the pin-fins and blockages were considered. Jet curvature can result in flow inclinations of as much as 45 deg–60 deg interacting with the pin-fins and the majority of the jet flow is skewed toward the inner side of the pin-fin. At the end-wall, the interaction with nearby structures, being blockages or pin-fins, alters the shape and profile of the flows. This alteration is in contrast to those around conventional pin-fin arrays which remain largely unaltered in the presence of nearby pin-fins.
