any of various rotary machines that use the kinetic energy of a continuous stream of fluid (a liquid or a gas) to turn a shaft
A rotary engine that converts the energy of a moving stream of water, steam, or gas into mechanical energy The basic element in a turbine is a wheel or rotor with paddles, propellers, blades, or buckets arranged on its circumference in such a fashion that the moving fluid exerts a tangential force that turns the wheel and imparts energy to it This mechanical energy is then transferred through a drive shaft to operate a machine, compressor, electric generator, or propeller Turbines are classified as hydraulic, or water, turbines, steam turbines, or gas turbines Today turbine-powered generators produce most of the world's electrical energy Windmills that generate electricity are known as wind turbines
Both the Parsons and Curtis turbines are suitable for driving dynamos and steamships directly
The flare of the nozzle causes expansion of the steam, and hence changes its pressure energy into kinetic energy
The steam is constrained to pass successively through alternate rows of fixed and moving blades, being expanded down to a condenser pressure of about 1 lb
The Curtis turbine is somewhat simpler than the Parsons, and consists of elements each of which has at least two rows of moving blades and one row of stationary

any of various rotary machines that use the kinetic energy of a continuous stream of fluid or gas to turn a shaft
A device used in the generation of electricity It has a shaft with blades at one end and electromagnets at the other Water or steam or some other energy source pushes the blades, which make the shaft and the magnets spin very fast The magnet end is surrounded by heavy coils of copper wire, and the spinning magnets cause electrons in the wire to begin to move, creating electricity
A machine for generating rotary mechanical shaft power from the energy of a stream of fluid (such as water, steam, or hot gas) Turbines convert the kinetic energy of fluids to mechanical energy through the principles of impulse and reaction

A mechanical structure with rotatable blades mounted onto its assembly and mechanically coupled to an electrical generator When a turbine is placed in the path of flowing water, steam, or moving air, the movement of the water, steam, or air across the blades causes them to turn The generator's armature rotates within a magnetic field which produces electrical energy at the terminals of the generator See ELECTRICAL GENERATOR

A bladed, rotating engine activated by the reaction or impulse, or both, of a directed current of fluid In electric power applications, such as geothermal plants, the turbine is attached to and spins a generator to produce electricity
Device that converts the flow of a fluid (air, steam, water, or hot gases) into mechanical motion for generating electricity
A turbine is a machine or engine which uses a stream of air, gas, water, or steam to turn a wheel and produce power. an engine or motor in which the pressure of a liquid or gas moves a special wheel around gas turbine, wind turbine (turbo ). Any of various devices that convert the energy in a stream of fluid into mechanical energy by passing the stream through a system of fixed and moving fanlike blades and causing the latter to rotate. A turbine looks like a large wheel with many small radiating blades around its rim. There are four broad classes of turbine: water (hydraulic), steam, wind, and gas. The most important application of the first three is the generation of electricity; gas turbines are most often used in aircraft
A machine in which the kinetic energy of the steam is transformed into direct rotary motion A reciprocating engine produces work by the relatively slow overcoming of resistance by the pressure of the steam up to the cut off and by the hyperbolic expansion of the steam up to the release while a turbine does its work through the impulse reaction of steam or steam jets at high velocity on rotary vanes
A device for converting the flow of a fluid (air, steam, water, or hot gases) into mechanical motion that in turn produces electricity
An item of equipment that converts energy within a fluid to mechanical energy on the output shaft Turbines can be designed to operate with either steam or gas
