dc.description.abstractThe characteristics of flow around slit-inserted cylinders were investigated using the three-dimensional large eddy simulation (LES). In the investigations, three different slit width-to-cylinder diameter ratios, i.e., s/D = 0.1, 0.2 and 0.3, together with regular cylinder were used. Slits were placed inside the cylinders with a zero-inclination angle, ? = 0o. The Reynolds number of the flow was ReD = 3900 based on the cylinder diameter, D, and free stream velocity, U?. The results presented that the jet flow emerging from the slits deviated in crossflow direction forming a biased wake flow downstream of the slit cylinders. Compared with the regular cylinder, relative per cent reductions in drag coefficients of the slit cylinders with s/D = 0.1, 0.2 and 0.3 were 3.1%, 11.3% and 6.5%, respectively. The rates of turbulence quantities in downstream wakes of the slit cylinders were reduced. Formations of shear layers in the downstream wake changed drastically as the slit width-to-diameter ratio, s/D, increased.
