Cross-Flow
The cross-flow turbine incorporates a long, tubular type turbine rectangular nozzle that sprays the pool at curved vanes even on a drum-shaped runner. The ocean passes by way of the blades twice, hitting a blade a second time declining in popularity. This turbine works the best for larger water flows with shorter drops. The cross-flow turbine has less efficiency than conventional turbines.

Propeller
Reaction turbines turn to both pressure and moving water to think of power. The runner is put directly within the water stream, which flows across the runner. These turbines work effectively for water employing a higher flow together with a lower drop. There are actually three strains of reaction turbines: the propeller, Francis and kinetic. The propeller turbine is known for a runner with six blades where the water constantly contacts, providing constant pressure. The blade pitches are generally fixed or adjustable. Like reaction turbine have their subcategories. The bulb turbine is sealed to the generator and placed into the tank stream. The straflo turbine grow a generator attached directly to it. The tube turbine has a penstock that bends before or right after the runner, directly connecting to your generator. turbine generators the Kaplan has adjustable blades and wicket gates, letting the turbine operate more widely (See References 1).

Kinetic Energy
Kinetic energy turbines, called draft tubes and diffuser tubes, believe in the kinetic energy in water rather than working energy out from the water. This feature works in rivers, channels, ocean currents and tidal waters. No alternations are needed to the liquid body, when the kinetic energy turbine depends on the water's natural pathway. The most efficient kinetic energy turbines have conical sections, yet the conical sections mustn't be too broad or flow separation will result. Flow separation is when this type of water all around the cone stops moving.

Francis Turbine
The Francis turbine has runners called vanes, which might be like buckets. You can get usually nine buckets. The river passes in your runner, allowing the runner to spin. The Francis has three other components referred to as scroll case, draft tube and wicket gates. pelton type turbine francis turbines are either proceed a receptive flume or associated with a penstock.
