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.
