Numerical study on a two-dimensional circular cylinder with a rigid and an elastic splitter plate in uniform flow

A two-dimensional incompressible viscous flow around a fixed or elastically supported circular cylinder with a splitter plate of attached rigid, hinged or elastic types, has been simulated by a finite difference method, to study the effect of splitter plate on the drag and vortex shedding frequency of the cylinder. The computation is carried out at Re = 1000, and the results are in good accordance with the available experimental data. The relationship between the unsteady flow patterns and hydrodynamic force coefficients is also discussed.
