Background and activities
The main objective is to investigate the impact of high amplitude pressure loading on the blade structure. The research also includes the development of efficient procedure to perform fluid-structure analysis in hydraulic turbine. Requirement of computational power is extremely high to perform structure analysis within hydraulic turbines. (HiFrancis)
I am involved in a research group (Francis-99) which provides open platform to the interested researchers to perform very challenging numerical simulations of hydraulic turbine. Under the Francis-99 workshop series, interested researcher will perform numerical simulations on the Francis turbine using their novel idea and the results will be presented in the workshop. Necessary experimental data, geometry of the complete turbine, and mesh are provided freely to the interested research groups.
I am also involved in pressure measurements and investigations of variable-speed Francis turbine. (FME HydroCen) Focus is to determine the unsteady pressure fluctuations at different locations in the turbine under variable-speed configurations. How to reduce the fatigue loading during load variation?
