Definition von turbine im Englisch Englisch wörterbuch
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
A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc
There are practically only two distinct kinds, and they are typified in the de Laval and the Parsons and Curtis turbines
The Parsons turbine is an impulse-and-reaction turbine, usually of the axial type
A rotary device that usually powers an electrical generator The turbine may be turned by water, wind or high pressure steam

The de Laval turbine is an impulse turbine, in which steam impinges upon revolving blades from a flared nozzle
A machine that has propeller-like blades which can be moved by flowing water or gas (including steam) thereby rotating a component in a generator to produce electricity
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
size is requisite for high efficiency, and the machine has therefore to be geared down to be of practical use
a machine that uses fluids to turn a wheel or cylinder to create energy, usually electricity
Part of an aircraft engine which converts the kinetic energy of moving air into rotational power
In efficiency, lightness, and bulk for a given power, they compare favorably with reciprocating engines
any of various machines in which the kinetic energy of a moving fluid is converted to mechanical power by the impulse or reaction of the fluid with a series of buckets, paddles, or blades arrayed about the circumference of a wheel or cylinder
A machine that converts the kinetic energy of a moving fluid (e g , pressurized steam) into mechanical energy (the rotating motion of a shaft)
(gen) A machine for generating rotary mechanical power from the conversion of ENERGY in a stream of fluid The fluid could be water, wind, or gas By passing the stream through a system of fixed and/or moving BLADEs, a drive shaft is rotated, which, when connected to a generator, creates an electromagnetic field that transforms the mechanical energy into electricity F - turbine S - turbina
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
{i} engine powered by a rotor revolving by means of the force of moving liquid exerted on the vanes of the rotor (fluids commonly used are water, steam, and air)

A device for converting the flow of a fluid (air, steam, water, or hot gases) into mechanical motion
A mechanism in a dam that rotates with the force of water and produces electricity
Machine for generating rotary mechanical power from the energy in a stream of fluid The energy, originally in the form of head or pressure energy, is converted to velocity energy by passing through a system of stationary and moving blades in the turbine
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
Some recent development of this type include turbines formed of several de Laval elements compounded as in the ordinary expansion engine
