Effect of Flow Parameters on Pelton Turbine Performance by Using Different Nozzles

Saif Aldeen Saad Obayes and Mohammed Abdul Khaliq Qasim
Abstract—The aim of this paper is to investigate experimentally the effect of different nozzles, water head and discharge on the performance of Pelton turbine system. The effect of five different nozzles with outlet diameters of (3.61, 5.19, 8.87, 12, and 14.8) mm has been studied. The tip and hub diameter of the Pelton wheel of (269.89, 221.29) mm has been used with different nozzles. A water pump was used to generated the pressure head and volume flow rate. The results show for every certain nozzle that when decreasing the water head lead to reduction in water discharge and this caused reduction in the torque, brake power, efficiency and the rotational speed. In addition, the results show that when increasing in nozzle diameter lead to increasing the discharge and reduction water head. While in the case of constant head of 15 m, the results show that the nozzle with diameter 8.87mm give the best the performance than the others, where the percentage increase in torque, brake power, efficiency and the rotational speed of the turbine are (62.2%, 66.48%, 60%, and 15.35%) respectively with the second nozzle with diameter of 5.19 mm.

Index Terms—Pelton turbine, water pump, electrical power, torque, brake power, nozzle.
