Effect of tripping wires on the hydrodynamics of a circular cylinder in uniform and shear flows

Abstract

Two-dimensional numerical simulations are conducted to examine the effects of tripping wires on the hydrodynamic properties of a stationary cylinder in uniform and shear flows at a fixed Reynolds number of 100. Three sets of numerical tests are carried out: 1) symmetric and asymmetric tripping wire arrangements in a shear flow; 2) symmetric arrangement of tripping wires of various diameters in a uniform flow; and 3) symmetric arrangement of tripping wires placed at a range of distances from the cylinder in a uniform flow. The results of each test are described in terms of hydrodynamic forces and vortex shedding frequency.
