Abstract

A simple way to decrease the drag and oscillating lift forces in the flow around a circular cylinder consists of positioning splitter plates in the wake of the flow. In our work, a geometry consisting of two splitter plates placed close to a circular cylinder was studied. The length of the splitter plates is equal to the cylinder diameter and they are positioned in a side by side configuration parallel to the freestream velocity, with their leading-edges aligned with the cylinder center. This flow was studied using two-dimensional direct numerical simulations, with the Spectral Element Method being employed to solve the incompressible Navier-Stokes equations for Reynolds numbers in the range between 100 and 350. The results showed a strong dependence on the Reynolds number, with the splitter plates being more beneficial at the higher values of Reynolds numbers considered.
