The effect of varying vortex settling basin (VSB) outlet configurations on the removal of sediment particles >75 μm was computationally investigated using ANSYS Fluent's Euler-Lagrange approach, which incorporated supervised optimization and was validated by physical modeling. A rectangular centroidal outlet was established with a low outlet weir a...

... blockage of intakes and outlets and abrasion of pumps/turbines, leading to inefficiency and increased downtimes and operational costs ( Brekke et al. 2003;Brink et al. 2006). Finding the optimal way of dealing with sediment at an abstraction works is of significance to sustainability and operational costs. The vortex settling basin (VSB) shown in Fig. 1 is a cylindrical fluidic device that offers a cost-effective alternative for a typical small-yield potable water rural abstraction scheme. The VSB tangential inlet generates swirling flow motion that forces heavier particles toward the wall (due to gravity), in which they spiral downward to the underflow, and consequently less sediment ...

Erosion wear is an important issue for a Francis turbine operating on rivers from the Himalayas, which directly hinders the utilization of hydropower. In this research, the severe erosion wear on the runner shroud of a Francis turbine is studied. The characteristics and physical mechanisms of the erosion wear on the runner shroud are investigated t...
