        This paper refers to the flow analysis of nozzle with spear for different nozzle opening of Pelton turbine. Experimental test was performed by using model turbine to find out the parameters during testing period. The flow rate, head and the rotational speed on the turbine shaft are measured for various nozzle openings covering a wide operation range. The best efficiency is 86% and output power of the model turbine is 110W. For water flow simulation of nozzle with spear by applying Computational Fluid Dynamics (CFD) software ANSYS CFX-14.5 are presented. The pressure and velocity distribution have also been obtained to study the effect of nozzle on flow pattern. The flow simulation has been carried out the standard k - ε turbulence model. And then, CFD simulation results with experimental value have been compared in this research.
