It is assumed that an averaged turbulent flow is horizontally layered in vicinity of the cylinder. In each layer the flow around the cylinder is modelled as a potential flow generated by a vertical dipole line. Flow in viscous sub-layer on the surface of the cylinder is neglected. The presented flow model is approximate; however it is simple for use. Trajectories of saltating particles near the cylinder were calculated. Further investigation of such flow will allow a determination of zones where solid particles will collide with the column. That might be useful for prevention of its damage or destruction. 000003655 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000003655 653__ $$asaltation of sand, flow around cylinder, logarithmic profile, dipole line, averaged turbulent flow. 000003655 7112_ $$aEngineering Mechanics 2013$$cSvratka (CZ)$$d2013-05-13 / 2013-05-16$$gEM2013 000003655 720__ $$aKharlamova, I.
