A boat propelled by wave energy

Posted by dane307 2260 days ago in Fluid Mechanics from http://www.forbes.com

Waves can be used for a lot more than surfing.

The Suntory Mermaid II is a 10-meter (33-foot) catamaran (a type of two-hulled boat) currently slowly propelling itself across the North Pacific solely using wave power. The boat is captained by Kenichi Horie, a 70-year-old Japanese marine adventurer who is attempting to sail it over 4,400 miles from Hawaii to Japan. The Mermaid is the first wave- ... Read More

eBook: Wetting and Spreading Dynamics (free download available)

Posted by teddyRIO 2260 days ago in Fluid Mechanics from http://www.ebook.bogybogy.com

Wetting and Spreading Dynamics explains wetting phenomena when a liquid partially or completely wets solid or immiscible liquid surfaces. Written for both newcomers and experienced researchers in the field, the book uses principles and terminology from colloid science, fluid mechanics, and thermodynamics to solve equilibrium and dynamic problems in wetting and spreading.
This book explains how s ... Read More

Summary of PIER-Funded Ocean and Wave Energy Research

Posted by dane307 2264 days ago in Fluid Mechanics from http://www.energy.ca.gov

This report summarizes Public Interest Energy Research Program-funded research in wave energy conversion and discusses the program's view on the next steps for research, as it relates specifically to the California context. To study the potential for wave energy, the waters off the coast of California were first broken into 10 one-degree latitude cells. For each cell, buoy data were statistically ... Read More

Old but Still Interesting: Pressure of Light Can Move Liquid

Posted by aqua 2264 days ago in Fluid Mechanics from http://www.livescience.com

Scientists have figured out how to create a jet of liquid with nothing but the power of light.

They shined a laser beam through a soapy liquid, producing a long jet that eventually broke up into droplets.

"I thought this was just so weird because I know when liquid is supposed to break up, and this one isn't doing it," said study team member Wendy Zhang, an assistant professor in physics a ... Read More

Turning Water into Fuel

Posted by Svalbard 2269 days ago in Fluid Mechanics from http://www.popsci.com

Last winter, inventor John Kanzius was already attempting one seemingly impossible feat-building a machine to cure cancer with radio waves-when his device inadvertently succeeded in another: He made saltwater catch fire. TV footage of his bizarre discovery (check out the video below) has been burning up the blogosphere ever since, drawing crackpots and Ph.D.s alike into a raging debate. Can water ... Read More

Estimating hydraulic properties of coastal aquifers using wave setup

Posted by dane307 2270 days ago in Fluid Mechanics from http://www.sciencedirect.com

Wave setup is the elevated mean water-table at the coast associated with the momentum transfer of wave breaking, which occurs generally over several days. Groundwater responses to wave setup were observed as far as 5 km inland in central Maui, Hawaii. The analysis showed that at times of energetic swell events wave-driven water-table overheights dominate low-frequency groundwater fluctuations ass ... Read More
