Özet
Sedimentation of particles on a pipe wall in developed turbulent flow is a rather common phenomenon in industrial processes. Various experimental investigations showed that the sedimentation velocity of particles is greatly affected by the roughness height and the friction factor. In this article, new expressions to calculate the friction factor and the sedimentation velocity of the particles in turbulent flow in rough pipes are suggested for the range of the Reynolds number, 10(4) less than or equal to Re less than or equal to 10(7) and the range of the dimensionless relaxation time, 10(-1) less than or equal to tau(+) less than or equal to 10(2), respectively. Comparisons of the suggested equations in this work with the published experimental data from the literature show good agreement. (C) 2002 Elsevier Science B.V. All fights reserved.
