Abstract: This study addresses the problem of erosive wear of Francis turbine runner of a typical power station located in northern Himalayan belt of India. Wear damage is determined using the erosion models of IEC-2009, IEC-2013, empirical assessment of Thapa and a methodology proposed in this research work. The proposed model introduces effect of relative velocity of turbine instead of characteristic velocity and also the effect of curvature of the blades by incorporating a parameter referred to as geometrical factor. The results obtained from the proposed model of erosive wear of the Francis turbine have been calibrated against Jhimrukh Hydropower Centre(JHC).
