dc.description.abstractA numerical study is performed to emphasize the influence of splitter plates on the wake of a diamond-shaped cylinder at Reynolds (Re) numbers of 80, 100, and 150. Dimensionless plate lengths (L) vary from L = 0.25D to L = 6D in order to explore the sensitivity of the flow structure to the inclusion of the splitter plate. Key insights are provided through flow streamlines, vorticity contours, drag coefficients, and wake thicknesses; offering a comprehensive understanding of the flow behavior. Three distinct flow regimes are identified depending on the plate lengths and Re number. Vortex shedding is attenuated gradually up to L/D = 1 for all Re. The rolling up vortices from the trailing edge of the plate generate different flow regimes at L/D = 1.5. Furthermore, a steady wake regime is observed for L/D = 2 and 4 at Re = 80 and 100, respectively. A decreasing trend of Strouhal (St) number with the increasing splitter plate length is observed even though non-monotonic behavior is discerned at longer lengths. This reduction in the fluctuations brings out the efficacy of the splitter plates in suppressing vortex shedding. The results demonstrate how passive flow control can be achieved with reduced base pressure of the diamond cylinder by adding splitter plates.
