PELTON TURBINE WITH TWO NOZZLES: DESIGN AND PERFORMANCE ANALYSIS

Abstract

This study utilized a laboratory-based Pelton turbine to investigate the impact of nozzle quantity on turbine power, torque, and efficiency. Analytical and empirical methods were employed to evaluate performance under 1- and 2-nozzle configurations, along with 21 turbine buckets. The findings revealed that increasing the number of nozzles led to higher rotational speed but reduced torque, which ultimately affected efficiency. The 1-nozzle configuration achieved a peak efficiency of 18%, while the 2-nozzle configuration produced more power but with lower efficiency. These results highlight the importance of optimizing nozzle count and water pressure regulation to enhance the performance of Pelton turbines in hydropower applications. This study provides valuable insights into nozzle design and configuration to maximize energy output from Pelton turbines and emphasizes the need to balance power, torque, and efficiency in turbine operation. Further optimization of these factors will support improved turbine effectiveness in harnessing the full potential of hydropower.
