An Investigation on the Tribological behavior of Ultrasonically Processed Carbon Black Inoculated AZ31 Magnesium Alloys

The silt concentration in Himalayan region is very high and the Kaplan turbine running in these rivers are usually seriously abraded. The appearance of silt enhanced the probability of cavitation. Under combined erosion (silt + cavitation), the performance of Kaplan turbine may be reduce which results in decrease in efficiency of the turbine. In present study Kaplan turbine rated capacity 7 MW is simulated for CFD analysis of combined erosion in Kaplan turbine. The simulation investigated for Kaplan turbine under various operation conditions namely; pure water, cavitation erosion, silt erosion and combined erosion.
