Abstract: In the current investigation, the effect of a splitter plate length on flow induced forces and heat transfer behavior of circular cylinder at low Reynolds numbers (20<=Re<=1000) was studied using a finite volume methodology on triangular unstructured grid. A significant reduction in the drag coefficient as well as the average Nusselt number was observed in the presence of splitter plate implying stabilization of the wake region and accordingly reduction of the vortex shedding. However, the conductive heat transfer was increased as a result of the extra heat transfer area generated by splitter plate, upon which the overall heat transfer of the system was improved.
