Abstract

The pressure loss of the flow with a stationary deposit bed is investigated experimentally and theoretically in this paper. The pressure loss increased as the mean velocity above the deposit bed and the dimensionless height of the deposit bed increased. Furthermore, the force balance model above the deposit bed was made in order to examine the relation between the behavior of saltating particles and the pressure loss of the flow with a stationary deposit bed. The components of this model consist of the shear stress at the pipe wall, the shear stress at the surface of the deposit bed, the shear stress due to rolling and sliding particles, and the shear stress in the collision of saltating particles with the surface of the deposit bed. The calculated values of the pressure loss by this model were in good agreement with the experimental results.
