S-turbines eliminate the need for a bulb housing by placing the generator outside of the water channel. This is accomplished with a jog in the water channel and a shaft connecting the runner and generator. The VLH turbine is an open flow, very low head "kaplan" turbine slanted at an angle to the water flow. It has a large diameter >3.55 m, is ...

When the speed of the runner is equal to the initial jet velocity, the torque is zero (i.e., when u = V i, then T = 0). On a plot of torque versus runner speed, the torque curve is straight between these two points: (0, pQDV i) and (V i, 0). [11] Nozzle efficiency is the ratio of the jet power to the waterpower at the base of the nozzle.
The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.
The Archimedean screw turbine is applied on rivers with a relatively low head (from 0.1 m to 10 m) and on low flows (0.01 m 3 /s up to around 10 m 3 /s on one turbine). Due to the construction and slow movement of the blades of the turbine, the turbine is considered to be friendly to aquatic wildlife.
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...
