Francis inlet scroll at the Grand Coulee Dam Side-view cutaway of a vertical Francis turbine. Here water enters horizontally in a spiral-shaped pipe (spiral case) wrapped around the outside of the turbine's rotating runner and exits vertically down through the center of the turbine. The Francis turbine is a type of water turbine.
MIT's millimeter size turbine will deliver 500–700 Wh/kg (820–1,140 kJ/lb) in the near term, rising to 1,200–1,500 Wh/kg (2,000–2,400 kJ/lb) in the longer term. [ 14 ] A similar microturbine built by the Belgian Katholieke Universiteit Leuven has a rotor diameter of 20 mm and is expected to produce about 1,000 W (1.3 hp).
The turbines were built by two partners of James Bay Energy (SEBJ). Units 1, 3, 5, 7, 10, 12, 14 and 16 were built by Marine Industries Limited (MIL), while units 2, 4, 6, 8, 9, 11, 13 and 15 were built by Canadian General Electric (alternators) and Dominion Engineering Works (turbines). The two groups have somewhat different characteristics.
The tangential water inflow of the mill race made the submerged horizontal wheel in the shaft turn like a true turbine. [1] A Francis turbine runner, rated at nearly one million hp (750 MW), being installed at the Grand Coulee Dam, United States. A propeller-type runner rated 28,000 hp (21 MW) The earliest known water turbines date to the Roman ...

The Capstone microturbine is a turboshaft engine with a single coupled shaft carrying the compressor, turbine, and generator. Idealized gas turbine operation is represented by the Brayton cycle. In this machine, intake air is drawn over the generator (G) to cool it and is pressurized in the compressor (C); the compressed air then passes through ...
