Based on the solid–liquid two-phase flow model, SST k-ω model, and Lagrangian equation model of particle motion, numerical simulations of the sediment–water flow in the injector of a large Pelton turbine were conducted. The distribu...
Pelton turbines frequently encounter significant sediment wear when operating in sandy river environments. The runner bucket of these turbines is particularly prone to wear, which results in considerable reductions in turbine efficiency and operation...
During the installation and operation of Pelton turbines, deviations of the jet centerline from the runner pitch circle can compromise turbine stability and efficiency. Utilizing design data from a Pelton turbine on China’s Dadu River, this stu...
The rapid shutdown of high-head and large-capacity Pelton turbines equipped with long penstocks often induces severe water hammer effects, threatening the structural safety of the diversion system. Traditional linear or simple piecewise nozzle closin...
Hydropower is a key source of electricity production for allowing the integration of intermittent renewable energy resources. Among the various hydraulic power plants around the world, the ones equipped with Pelton turbines already provide large flex...
This study addresses the critical challenge of sediment-driven degradation in aging hydropower infrastructure by implementing a novel Digital Operational Technology modernization framework at the AES Chivor Hydropower Plant in Colombia. While convent...
