| Abstract: | Measures for improving turbine abrasion conditions are provided by analyzing silt abrasion mechanism and conditions in turbine. Design method for runner bucket of Francis turbine in sandy water is studied based on two dimensional theory.Runner flow field computation,bucket numerical integration and bucket thickening are conducted by reliable numerical computation method. Effectiveness and abrasion prediction are carried out for runner during preliminary design.Computer aided system for hydraulic design of Francis turbine runner bucket in sandy water is developed. An instance for application of the designed software is presented. |
