Effects of cylinder Reynolds number on the turbulent horseshoe vortex system and near wake of a surface-mounted circular cylinder
Kirkil, Gökhan; Constantinescu, George (Amer Inst Physics, 2015)The turbulent horseshoe vortex (HV) system and the near-wake flow past a circular cylinder mounted on a flat bed in an open channel are investigated based on the results of eddy-resolving simulations and supporting flow ... -
Flow and Turbulence Structure Around an In-Stream Rectangular Cylinder with Scour Hole
Kirkil, Gökhan; Constantinescu, George (TSINGHUA UNIV, 2013)An eddy resolving technique is used to reveal the unsteady dynamics of the coherent structures present in the flow field around an in-stream vertical cylinder with a scour hole at a channel Reynolds number of 240000. Such ... -
A Numerical Study of Shallow Mixing Development over Flat Surface and Dunes
Kirkil, Gökhan; Constantinescu, George (TSINGHUA UNIV, 2013)Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a smooth flat bed and dunes. ... -
A numerical study of the laminar necklace vortex system and its effect on the wake for a circular cylinder
Kirkil, Gökhan; Constantinescu, George (Amer Inst Physics, 2012)Large eddy simulation (LES) is used to investigate the structure of the laminar horseshoe vortex (HV) system and the dynamics of the necklace vortices as they fold around the base of a circular cylinder mounted on the flat ...
