One of the results of the experimental model is shown in the diagram below (Fig. 10), namely the increase of available hydraulic power due to the ejector effect detected in the course of the measurement program. Fig. 10 Experimental model – hydraulic performance with and without ejector [3] At the operation point with the highest flow rate the hydraulic power available for the turbine is still around 22 % higher than compared to the situation without ejector.
