Eddy sentence example
Hence when a current is passed through the meter, the armature rotates and increases its speed until the driving force is balanced against the retarding force due to the eddy currents in the copper brake disk.
Numerical Equations These are based on the diffusion equation in one dimension, where is the eddy viscosity.
Observational methods, e.g. eddy correlation techniques to measure turbulent fluxes or measurement of mean profiles to infer turbulent transport.
The original calibration and corroboration of the SPA model was against long-term eddy covariance data from the Harvard Forest, Massachusetts.
This may represent sediment supplied by cliff erosion being entrained by the westward flowing recirculating eddy (Dyer, 1971 ).Advertisement
There was a right hand bend which formed a beautiful eddy over which hangs a very large bush.
The Shambles is within the area of an anticlockwise tidal eddy east of the headland.
Again Eddy is chopped down and this time Sleaford's number 2 is entered into the referee's notebook.
Primary production rates were slightly higher inside than outside a Storm eddy studied in the Ne subtropical Atlantic in April 1999.
The 20th of March showing four eddy whirlwind events.Advertisement
If this could be co-ordinated and utilized without dissipation, the gas might conceivably be restored to its initial state; but in practice violent local differences of pressure and temperature are produced, the kinetic energy is rapidly converted into heat by viscous eddy friction, and residual differences of temperature are equalized by diffusion throughout the mass.
When these last coils are traversed by an alternating current they induce local or eddy currents in the disk.
Again the shunt circuit must have practically zero inductance and the series or current coil must be wound or constructed with stranded copper wire, each strand being silk Covered, to prevent the production of eddy currents in the mass of the conductor.
But if a dog is sent in there will be a sudden yelp, the splash from a big tail, and a widening eddy.
Now sequestered at this quaint rustic getaway, Eddy 's ready to greet the uninitiated.Advertisement
Primary production rates were slightly higher inside than outside a Storm eddy studied in the NE subtropical Atlantic in April 1999.
Magnetic ceramics The steel alloys used for transformer cores have high resistivity in order to prevent substantial eddy current losses.
Induced or eddy currents are thus created in the copper disk, and the reaction of these against the magnetic field offers a resistance to the rotation of the disk.
It may even eddy backwards, as indicated by the curved arrows, and it is no uncommon thing, in walking up a steep hill in the contrary direction to the flight of the clouds, to find that the rain is coming from behind.
The heart of a normal eddy current separator is a powerful permanent magnet that revolves at very high speed.Advertisement
For the application of this method to a series of loads Prof. Eddy's paper must be referred to.
In Se p tember of that year he discovered that the force required for the rotation of a copper disk becomes greater when it is made to rotate with its rim between the poles of a magnet, the disk at the same time becoming heated by the eddy or "Foucault currents" induced in its metal.
Among the principal buildings are the state capitol, the state library, the city hall, the county court-house, the post-office, the Fowler public library, the state hospital, the state prison, the Centennial home for the aged, the Margaret Pillsbury memorial hospital, the Rolfe and Rumford asylum for orphan girls, founded by the countess Rumford, and several fine churches, including the Christian Science church built by Mrs Eddy.
The current to be measured passes transversely across the disk and causes it to revolve in the magnetic field; at the same time the copper brake, geared on the same shaft, revolves in the field and has local or eddy currents produced in it which retard its action.
It consists of a disk of aluminium, the axis of which is geared to a counting mechanism and which runs between the poles of permanent magnets that create eddy currents in it and therefore exert a retarding force.Advertisement
For specimens of large sectional area it is necessary to apply corrections in respect of the energy dissipated by eddy currents and in heating the secondary circuit.
The framework and case of the instrument must be completely non-metallic, else eddy currents induced in the supports will cause disturbing forces to act upon the movable coil.
The Atlantic anticyclone is, therefore, at its weakest in winter, and on its polar side the polar eddy becomes a trough of low pressure, extending roughly from Labrador to Iceland and Jan Mayen, and traversed by a constant succession of cyclones.
Since the eddy currents induced in the disk are 90 degrees in phase behind the inducing field, the eddy currents produced by the main coil are in step with the magnetic field due to the shunt coil, and hence the disk is driven round by the revolution due to the action of the shunt coil upon the induced currents in the disk.
The Carlsbad reservoir and diverting dam in Eddy county and the Rio Hondo canals and reservoir in Chaves county were completed in 1907 and are capable of supplying water to tracts of 20,000 and 10,000 acres respectively.
