Abstract

<p>In the hydraulic transportation of solid-liquid flow in the conduits, the authors have proposed that to place the discharging plates in the flow area is valid to transport particles piled up. In the previous paper, we examined the effects of interval length of discharging plates while the plates were used under the experimental condition that was these plates were not inserted particles bed. However, practically the discharging plates have been used under the circumstance that is these plates are inserted particles bed. Therefore, in this paper, we examined the effects of interval length of discharging plates while the plates were used under the experimental condition that was these plates were inserted particles bed. As a result, it was found that the optimum interval length of discharging plates in current installation depth of the discharging plates. In addition, it was revealed by the visualization of particles behavior that the circumstances of the scouring boundary change by the interval length of discharging plates.</p>
