| Abstract: | CFD simulation of three-dimensional unsteady turbulent flow through a Francis turbine HLA351 runner with long and short blades was conducted with initial steady flow conditions,and the simulation data of pressure fluctuations on various components were analyzed in details.The results show the details of well-predicted flow field in the runner and the pattern of fluctuating pressure generation and propagation in the turbine.These results would provide a guideline for turbine design and optimization. |
| Keywords: | hydraulic machinery pressure fluctuation FLUENT full filed unsteady |
