Vertical concentration distributions of solids conveyed in Newtonian fluids can bovi-shield gold fp 5 l5 be modelled using Rouse-Schmidt type distributions.Observations of solids conveyed in turbulent low Reynolds number visco-plastic carriers, suggest that solids are more readily suspended than their Newtonian counterparts, producing higher concentrations in the centre of the pipe.A Newtonian concentration profile model was read more adapted to include typical turbulent viscosity distributions within the pipe and particle motion calculated using non-Newtonian sheared settling.Predictions from this and the unmodified model, using the same wall viscosity, are compared with the chord averaged profile extracted from tomographic data obtained using a 50 mm horizontal pipe.
