Abstract

A RECTANGULAR ROD is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of RECTANGULAR ROD on developing VORTEX SHEDDING downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary layer on STROUHAL NUMBER and the contrary effect of the boundary layer on VORTEX SHEDDING from the RECTANGULAR ROD are studied. Results show that as the RECTANGULAR ROD enters into the flat plate boundary layer, vortex generation from the closest side of the rod reduces, thereby reducing the STROUHAL NUMBER as well. Finally, when the RECTANGULAR ROD sticks to the flat plate, a stationary wake forms downstream the rod and sticks to the flat plate. Meanwhile, the boundary layer over the flat plate is disturbed effectively and heat transfer coefficient from the flat plate is enhanced by an average of 50% and up to 200% in some places, locally.
