To analyse duty points dropdown when centrifugal pumps run with cavitation on their suction side, experiments were conducted on a pumping station (PS) rig, where up to three variable speed driven pumps can run in parallel-coupling. The PS rig is equi

The computational efficiency of various nature-inspired algorithms is compared here for a specific hydropower optimization problem, selected as test-case due to its accurate reference solution yielded by the Newton-Raphson method. The above test-case

The paper presents an EPANET model of a groundwater well field. The method used in the simulations to model the variation of the hydrodynamic levels in wells as a function of the pumped flow rate is discussed, and a comparison to previous simulations

Many researches are currently addressing issues of optimizing the groundwater extraction systems, including the pumping equipment. One of the problems is that the flow rate extracted from the well must be smaller or equal to the optimum well flow rat
