ABSTRACT:
The turbine has an ambient pressure runner rotatable about a vertical axis. An annular row of radially curved vanes extends between the runner periphery and a center discharge. A surrounding volute directs an accelerated flow of water to the runner periphery with flow conditions such that supercritical flow enters the runner and is maintained across each vane rear face. These operational conditions are dependent upon volute design, available water head values, water entry angle, number of vanes and runner vane design.
