Penetration of intermittent power often disrupts the power grid network. Consequently, hydraulic turbines are needed to pass through transient conditions such as load variation, start-stop, total load rejection, and spin-no-load. This induces fatigue to the blades and affects the life of the runner. The fatigue is induced by high amplitude unsteady pressure pulsations developed during the transients.
Under the postdoctoral research work, fluid structure analysis of a high high Francis turbine (specific speed=0.27) will be performed. Detailed mechanical analysis of the runner will be carried out under different operating conditions.
