Abstract Schlieren photography has been used many years in physics; however it has proved to be exceptionally valuable in the study of ultrasonic waves in liquids. Part of the reason for its value is that many of the ultrasonic phenomena studied have their optical analogues. Thus, when one studies ultrasonic images he actually is studying a general ...
Reactive power,is the part of complex power that corresponds to storage and retrieval of energy rather than consumption.On an AC power system, there are two kinds of power - real power that actually does work, and reactive power that enables transformers to transform, generators to generate, and motors to rotate. 7. Demand, also known as Apparent power, is the ...
Wave energy converters are generally placed in a very harsh environment and are hard to access due to their location and/or unfavorable weather conditions. With this in mind a full-scale wind tunnel test facility capable of simulating a variety of wave heights and wave periods has been built to fully test and validate Aquanet's ...
Upwards air-motion associated with gravity-waves may also generate altocumulus cells. Carey et al. (2008) observed that mid-latitude altocumulus layer clouds were of mixed-phase composition on more than two-thirds of occasions and that mixed-phase conditions began within a few lens of metres of observable cloud top. ...
To further aid research and development projects, Ohmsett’s Wave Generator was recently upgraded to create waves following computer generated spectra such as JONSWAP and Pierson-Moskowitz, resulting in waves that more closely simulate ocean waves. ...

This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems ...
Over the past few months the marine industry has witnessed a number of significant commercial developments from the acquisition by Siemens last year of Marine Current Turbines to Alstom's purchase of Tidal Generation Limited (TGL) a few weeks ago. The purchase of TGL builds on Alstom's purchase of a 40% stake in wave energy company, AWS, in 2011. ...
Here represents one of the best spots to harness the UK's wave resource at potentially the lowest cost. The research has found that if we were to put a line of some 1,000Km of wave devices from the edge of the Rockall Trough over the top of Scotland we would be able to generate almost 100TWh of electricity a year. ...
When an internal fault occurs in a synchronous generator, the symmetry between the parallel paths of the winding is broken and different currents flow in them, due to unsymmetrical magnetic linkage between the stator windings. ...
However, there exist inherent errors for the estimation of the true location of the impact since it is highly dependent on the plant personnel's decision to determine the arrival time differences of the generated wave group among the neighbouring sensors. To overcome this problem in this study, the two-dimensional approach has been proposed and applied to ...
