| Abstract: | 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. |
| Description: | In this research optimization of Francis runner was conducted in three steps. Initially optimization of size of meridional profile was done. In this initial phase optimization was performed on the basis of obtained runner efficiency. After obtained runner of best meridional profile, lean angle of the runner was varied from -10o to 10o. -5o lean angle has performed best on the basis of efficiency. Then taking the runner design 600 design samples were created using Latin Hypercube Sampling (LHS) techniques. |
