Abstract

In this paper an equation of the deposition velocity in a bent pipe is derived by using some assumptions related to the particle free flight model which was used to derive the equation of deposition velocity in a horizontal pipe. In the equation for bent pipe a correction factor for the secondary flow induced by the centrifugal force is introduced and determined for the equation to agree well with the previous experimental data. The validity of the equation is discussed by comparison with the available experimental data. A rebound function for solid particles in the bend is empirically derived by modifying the rebound function obtained for a vertical pipe and the applicability of the function is also discussed.
