In recent years, the interest in developing new technologies to produce energy with low environmental impact by using renewable sources has grown exponentially all over the world. Devices that derive electricity from the sea (currents, waves, etc.) are of particular interest and can be modeled accurately with FLOW-3D. Learn more about modeling both wave energy and coastal protection.

The Lancaster University's website provides the following information:

"The WRASPA, or Wave-driven Resonant, Arcuate-action, Surging Power Absorber, is a hinged device which operates in Pitch-Surge. It is envisaged that the device will operate in water depths of 20-50m.

The device has undergone an initial proof of concept set of tests and signs of power capture are in line with expectations. A joint research program of shape optimization, funded by the Joule Centre in Manchester, is currently being pursued at Lancaster and Manchester Metropolitan Universities."

A Pelton wheel is described in Wikipedia as follows: "The Pelton wheel is among the most efficient types of water turbines. It was invented by Lester Allan Pelton (1829-1908) in the 1870s, and is an impulse machine, meaning that it uses the principle of Newton's second law to extract energy from a jet of fluid."
