Abstract
Very low-head hydropower sites are abundantly available on small rivers, streams, irrigation canals, headworks or at wastewater facilities. However, lack of economically and ecologically viable technologies has been impeding these sites from being utilised for hydropower. The Zuppinger water wheel, with its high efficiencies over a
wide operating range, is a potential device for very low-head applications. The efficiencies of around 75 % quoted in the literature reflect that there still exists a potential to improve the wheel performance through a better
understanding of the flow physics around the wheel. For this reason, a testrig with a Zuppinger water wheel model and a non-intrusive velocity measurement technique, Particle Image Velocimetry (PIV) is developed. In
this paper, the experimental set-up, PIV instrumentation, and the special requirements on the set-up imposed by the water wheel are discussed and preliminary results are presented.
