Abstract: “The flow characteristics of inline and one slotted cylinder placed in a fin tube heat exchanger model are experimentally investigated using Partical Image Velocimetry (PIV) for Reynolds numbers of 1500 and 4000. In this study, the Reynolds number is calculated based on the cylinder diameter. Qualitative flow visualization was initially employed in order to observe the overall nature of the vortical flow patterns of cylinders. The flow interactions in the streamwise bases of the cylinder with a flat plate surface results in two dimensional vorticity <>, streamline topology <> and velocity vector map behavior.”
