Numerical investigation of fluid flow characteristics past a circular cylinder attached with a splitter plate for three different configurations such as splitter plate attached on front side, rear side and on both sides of the circular cylinder are performed. Simulations are carried out using Streamline upwind/Petrov-Galerkin (SUPG) based finite element method in laminar regime. The range of Reynolds numbers (Re) is varied from 50 to 200 and the plate length (L) is varied from L/D = 0 to L/D = 6, (D diameter of the cylinder) . The effect of splitter plate length on parameters like lift and drag are studied.
