Wind tunnel study demonstrates horseshoe vortex control in a cylinder-plate juncture, suggesting effective boundary layer separation and adverse pressure mitigation.
Control of horseshoe vortex in the circular cylinder-plate juncture using vortex generator (VG) was studied at ReD (where D is the diameter of the cylinder) = 2.05 X105. Impact of a number of parameters e.g., the shape of the VG\'s, number of VG pairs (n), spacing between the VG and the cylinder leading edge (L), lateral gap between the trailing edges of a VG pair (g), streamwise gap between two VG pairs (SVG) and the spacing between the two VG\'s in parallel arrangement (ZVG) etc. were investigated on the horseshoe vortex control. The study is conducted using surface oil flow visualization and surface pressure measurements in low speed wind tunnel. It is observed that all the parameters studied have significant control effect, either by reduction in separation region or by lowering the adverse pressure along the symmetric axis upstream of the juncture.
