The Francis turbine is a highly prevalent choice in hydropower generation in Nepal due to its capacity to operate efficiently across a wide range of conditions i.e. large domain of head and flow rate. Traditional design techniques, such as the Bovet method, rely on empirical equations to determine the turbine's meridional profile based on hydrological factors which can be further optimized. Evaluating the runner's performance involves considering factors such as efficiency, resistance to cavitation, erosion resistance, part load performance and more. To enhance a turbine's performance for a specific site, it can be optimized by adjusting various design parameters.
