Development of a high specific speed Kaplan pit-type turbine - numerical and experimental verification

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Power generation in irrigation channels and at other low head locations becomes more interesting due to the still increasing demand for green energy. For this kind of application a low-cost standardised turbine concept was developed with a high specific speed Kaplan pit-type turbine with a belt drive as core component. The 3-blade runner design was tested during a model test according to IEC 60193 [1]. The optimisation of the runner was realised by means of CFD with a special focus on the unfavourably high susceptibility of cavitation and pressure pulsation for such a high specific speed unit.
