Popis: In order to clarify effects of the divergent angle θ upon the hydraulic losses ξm in heterogeneous sand-water two-phase flows through divergent pipes, systematic experiments on ξm and the corresponding flow patterns are carried out for several θ, sand concentrations Cv and average downsream velocities Vm2. Here, we discover the interesting fact that for θl=60°, the ratio (ξm)^^- of ξm to the water flow counterparts ξw is fairly close to one, while ξm decrease a little for θ≥90°. The behavior of losses is also discussed.
