Webb26 feb. 2024 · This paper presents several multiphase and free-surface flow simulations for a Pelton wheel-scaled model. The main result of the numerical simulations was the shaft torque produced. An experimental investigation for four different rotational speeds at design-point condition of the turbine was performed in order to validate the … Pelton's ideas for improving the turbine water wheel came from his studies of mining equipment and operations in California's gold rush country. Summary descriptions of the local technology observed by Pelton, and of the science by which his turbine water wheel extracts kinetic energy from a coursing mountain stream follow...
