| Abstract: | This paper is focused on pressure fluctuation in 1000MW model Francis Turbine.Under 8.47mm guide vane opening,the unsteady numerical simulation is carried out in following twounit-speed:58.8r/min.We study the pressure fluctuation in the different areas of Francis Turbine,and the propagation law along the flow direction as well.How much the rotational speed of runner will influence frequency as well as amplitude of pressure fluctuation is showed in this paper. |
