At low and medium velocities the flow resistance increases with the increasing concentration of solids, at high velocities the effect of the concentration can be opposite. An intensive turbulent and even long time laminar shearing result in a significant decreasing of the laminar/turbulent transition velocity and flow resistance in the laminar region. The effect of shearing is more significant for higher slurry concentration."@en . . . . "[166D0F66B39C]" . "Vlas\u00E1k, Pavel" . .
