Hydropower plants (HPPs) contribute a significant share of Russia’s electricity generation. With the prospects developing this sector and harnessing hydroenergy potential, it is necessary to consider methods for modernizing hydroelectric installations. This article examines new method regulating active (Pelton) turbines based on modifying nozzle flow rate through ejection spent liquid from runn...

Based on the solid–liquid two-phase flow model, SST k-ω and Lagrangian equation model of particle motion, numerical simulations sediment–water in injector a large Pelton turbine were conducted. The distribution rules pressure, velocity, erosion rate, location obtained by analyzing characteristics sediment injector. results revealed that velocity trend water inside cylindrical jet exhibited nonl...
