Oscillatory flow around a large sphere resting on a plane and rough bottom is simulated by means of direct numerical simulations of continuity and Navier-Stokes equations. The bottom roughness is provided by a layer of spherical particles, the size of which is much smaller than the radius of the large sphere, arranged in a hexagonal pattern. To...

The oscillatory flow around a spherical object lying on a rough bottom is investigated by means of direct numerical simulations of the continuity and Navier-Stokes equations. The rough bottom is simulated by a layer/multiple layers of spherical particles, the size of which is much smaller that the size of the object. The period and amplitude of...
