This paper describes the design of four different specific speed microhydro propeller turbines operating at heads between 4m and 9m, and their application to a wider range of heads and outputs by scaling. The features are specifically tailored for ease of manufacture and uniquely resistant to...

This paper describes the design of two different specific speed microhydro turbines operating at heads between 6 and 12m, at small scale and up to heads of 50m at larger scales. The features are specifically tailored for ease of manufacture and uniquely resistant to debris blockage. Test...
