Einar Agnalt, Igor Iliev, Bjørn W. Solemslie, and Ole G. Dahlhaug, On the Rotor Stator Interaction Effects of Low Specific Speed Francis TurbinesThis paper has just been published by the International Journal of Rotating Machinery.

In this paper we have experimentally verified the rotor stator interaction in a low specific speed Francis model turbine and a pump-turbine utilizing pressure sensors in the vaneless space and in the guide vane cascade. The main findings show that the pressure fluctuations in the guide vane cascade are mainly controlled by throttling for the low blade loading case and the rotating runner pressure for the higher blade loading case
