Recently, turbines operating in hydro power plants are required to undergo renovation and modernization due to their age exceeding 30 years. In the process of renovation or moderniaztion, a performance test of the scaled-down in necessary to verify the performance of the real-size model. This model test method, with criteria that is simillar to that of a real turbine, is the most economical and important metho. Furthermore, the shape of the runner and guide vane can be modified or replaced easily. However, during the process of modernaiztion, the components with the spiral casing and draft tube are impossible to repair of replace because of the buried ground. Thus, in this study, numerical analysus us conducted to investigate the hydraulic performance based on the diference between the two-dimensional computer-aided design(CAD) shape and the real three-dimensional scan shpae of the spiral casing and draft tube. |
