The space between the rotor and stator is called the ‘air gap’, where a rotating electromagnetic field is produced by three-phase AC current flowing in the machine windings. The rotating speed of the magnetic filed is related to the synchronous speed ns, which depends on the frequency of ...
Also during a certification test, the damaged area due to cracking in the blade was located due to the sound of the cracking mechanism [56]. Fatigue tests can also be monitored, as [58] presents; such as the sound produced due to stress released waves or energy dissipation using ...
When the Wind Blows: Directed by Jimmy T. Murakami. With Peggy Ashcroft, John Mills, Robin Houston, James Russell. A naive elderly British rural couple survive the initial onslaught of a nuclear war.
Understanding the interactions between ionized matter and neutral particles is a prerequisite for discovering their impact on natural phenomena. One such phenomenon is the electric wind, which supposedly occurs due to the charged particle–neutral coupli

The drivers of the evolution of the South Asian Monsoon remain widely debated. An intensification of monsoonal rainfall recorded in terrestrial and marine sediment archives from the earliest Miocene (23–20 million years ago (Ma)) is generally attribu
CleanTechnica is the #1 site in the US for cleantech news & commentary. We focus on solar energy, wind energy, electric cars, and other clean technologies.
Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in places desi...
Wind generation is currently the major form of new renewable, generation in the world. The wind power is totally dependent on wind flow, due to randomness and uncertainty of wind flow, thewind power generationis quite fluctuating in nature and large scale wind farms may cause significant impact...
ERA5 is produced by the Copernicus Climate Change Service (C3S) at the European Centre for Medium-Range Weather Forecasts (ECMWF). ERA5 is the fifth-generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1940 to the present. It provides hourly estimates ...
