Abstract
As great hydro power potentials are already exploited in Germany the main focus Is on local small scale hydro power. Various concepts for such plants exist; among these Is the water vortex power plant which Is subject to this work. Designs for the vortex chamber, the turbine or the Inlet and outlet configuration are barely available. A design model was developed and according to this a physical model has been set up at scale 1:9. Different quantities were varied to Identify determining parameters. Velocities were measured In the vortex chamber and the performance of the power plant was evaluated. The outlet opening has the greatest Influence on the velocity distribution In the vortex chamber and on the turbine efficiency coefficient (greatest = best) which was approx. 0.5. The efficiency Is strongly depending on the flow depth In the inlet channel. The power plant with an overall efficiency of approx. 31 % is suited for small potential energy heads.
