Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.
This paper reports combined experimental and numerical
investigations performed to study the effect of upstream splitter
plate on drag reduction of a circular cylinder. The influence of
spacing between the cylinder and splitter plate (aspect ratio)
and thickness of the splitter plate (thickness ratio) on the flow
characteristics of the cylinder is analyzed and discussed. The
mathematical model governing the problem is numerically
solved using a commercial computational fluid dynamics
package ANSYS 14. The simulations have been carried out for
Re=20,150 and 6×104 so as to cover the laminar regime. In
order to validate the numerical model, experiments are
performed by placing the cylinder along with the splitter plate
in a low speed subsonic wind tunnel.
