Coherent structures in oscillating turbulent boundary layers over a fixed rippled bed
(2013)Coherent structures generated by oscillating turbulent boundary layers with or without a unidirectional current over a fixed, rippled bed are presented. The effect of ripple height and current intensity on the characteristics ...

Effect of turbulent pulsating flow around a near-wall submerged cylinder on the potential motion of bed and suspended loads
(International Society of Offshore and Polar Engineers, 2016)In the present work, the pulsating flow around a submerged cylinder close to the impermeable seabed is examined by means of Large Eddy Simulations (LES). A Reynolds number equal to Re = 5000 is considered, based on the ...

Lagrangian particle dispersion in turbulent flow over a wall mounted obstacle
(2009)Large-eddy simulations (LES) of particle-laden turbulent flows are presented in order to investigate the effects of particle response time on the dispersion patterns of a space developing flow with an obstruction, where ...

Large Eddy Simulation of near-bed pipelines in oscillatory flow
(2018)A series of unsteady, three-dimensional numerical simulations of the incompressible, oscillatory flow around a near-bed pipeline is presented. A flow at Reynolds number equal to Reαo=20,000 with respect to the oscillatory ...

Large eddy simulation of sediment transport for the pulsating flow past a cylinder over a horizontal bed
(International Society of Offshore and Polar Engineers, 2015)In the present work, the suspended, pulsating incompressible flow past a submerged cylinder was examined by means of Large Eddy Simulations (LES). A layer of sandy inertial particles was allowed to move between the cylinder ...

Large-eddy simulation of wave turbulent boundary layer over rippled bed
(2012)Large-eddy simulation (LES) of turbulent boundary layer induced by external oscillatory flow without or with a unidirectional component over rippled bottom is presented. These flows represent prototype turbulent flows of ...

MHD flow past a circular cylinder using the immersed boundary method
(2010)The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...
