Bed-Load Transport in Circular Pipe with Deposit Bed

Abstract

The flow resistance and bed-load discharge in a circular pipe with deposit bed is investigated by numerically analyzing with algebraic stress model of turbulence. The present calculation has clarified shearstress along the boundary including the surface of the deposit bed, which distributes transversely. By applying Swiss-formula for bedload transport, the local rate of bed-load transport is estimated, and then the total bed-load discharge is evaluated by integrating the local rate. The results were well consistent with the previous experimental data.
