Particle fluctuation intensities in sediment-laden flows

摘要

By employing the kinetic theory of solid-liquid two-phase flow, the velocity distribution of sediment was discussed and the theoretical results of the mean square value of the particle peculiar velocity in axis direction and vertical direction were obtained. The comparison of the experimental results of particle motion in horizontal pipe and the calculated results showed satisfactory agreement. The present study is unique not only in simulation of particle fluctuation characteristics in sediment-laden flows, but also in examination of the relationship between the fluid fluctuation intensities and particle fluctuation intensities. which reveals the coherence characteristics of particle and fluid fluctuations in dilute solid-liquid two-phase flows with tine sediments, (C) 2002 Elsevier Science Ltd.
