Abstract

Virtual hydraulic turbine method has become a very powerful technique to capture minor details of the flow which are impossible in the physical model testing and overcome the limitations of the physical laboratory setup; therefore, the current study conducted on the virtual hydraulic turbine by using Star ccm+ simulation code combined with CATIA V5 computer aided design software to improve the operation of the turbine according to the analysis results to establish the optimal number of the runner blades for the chosen turbine. The internal flow simulation results are used to characterize the turbine performance for a different number of blades. Six different turbine runners of 15, 20, 25, 30, 35 and 40 blades were investigated. According to current study, the most effective number of blades noticed was 30 blades
