Objectives
- To develop variable speed Francis turbine for Himalayan region with high sediment yield for sustainable operation.
- To conduct performance analysis of Francis turbine with a hill diagram at variable speed operation with a case study of a hydro turbine range in medium to high specific speed.
- To investigate likelihood of erosion in the hydraulic components of turbine at synchronous and variable speed operation modes.
- To improve sediment resistance of turbine with optimization of hydraulic parameters and modification in blade surface geometry.
- To develop an experimental setup for analysis of optimized design at laboratory conditions.

Expected Outcomes:
The expected outcomes of the study are mostly quantitative which should improve the hydropower scenario in Nepal with proven methods to operate variable speed Francis turbines. The study focuses on numerical and experimental techniques to test and prove hypotheses which will establish substantial resources to carry further research works in similar area. But the most intended outcome is to have
fundamental understanding and methods to resolve one of the significant problem, sediment erosion, for Nepalese hydropower plants.
