Recently, a rotating hydraulic pressure machine (‘Staudruckmaschine’) has been suggested by an Austrian inventor for the exploitation of low head hydropower with power ratings of 100 1000 kW, and head differences below 2m. The inventor could however not produce a consistent theory to explain the function of the machine nor was any performance data published.
At the University of Southampton, we have developed a theory which explains the governing principles of a rotating hydraulic pressure machine and highlights the ways to improve the principle. Physical model tests are currently under way to make this a feasible proposition. A detailed report of the work so far is available here (currently in German only).
