Since the introduction of the marine propeller in the early 19th century, cavitation during operation has been a limiting factor in the efficiency of ships. Cavitation in marine propellers develops ...

The area ratio is expressed as a percentage of a solid circular disc. “For instance, if the blade area is too small, the propeller will suffer from cavitation which leads to noise, vibration and loss ...

As part of this new alignment, Sharrow Marine will join upcoming ADS-sponsored trade shows, allowing industry stakeholders ...

Killer whales hunt fish with clicks and buzzes—they choose and chase their prey with sound waves. But a mundane feature of ...

Looking ahead, the researchers believe the same principles can be applied to assessing URN from plan drawings, enabling designers and builders to model and predict the noise created by ships before ...

Invented by Greg Sharrow, the Sharrow Propeller has solved the most basic problem of rotary propulsion, eliminating tip cavitation and vortices, and offering significant performance gains over ...

The increased pressure under the hull, due to the stern flap, can also serve to suppress propeller cavitation and reduce thrust breakdown losses at higher speeds. The stern flap effect ...

The increased attraction to cavitation machines stems from their non-invasive approach to fat reduction and skin texture improvement. They use ultrasound waves to disintegrate fat cells ...
