Vertical Wind Turbines May Boost Offshore Power
2012-07-31 15:53:42

Brett Smith for redOrbit.com - Your Universe Online A once-promising wind turbine prospect is getting a second look as engineers attempt to refine the technology for use in offshore power generation. Modern wind power is primarily generated by horizontal axis wind turbines (HAWT), but in the 1970s and 80s, during the early stages of wind power technology, another design was actively pursued because of its simplicity and reliability. Vertical axis wind turbines (VAWT), which have blades...

Aircraft morphing, especially in the case of the variable camber airfoil, has potential from the viewpoints of both fundamental aerodynamics and flight application. In the field of aerodynamics, the use of a variable camber airfoil can improve aircraft flight performance and allow efficient multiple missions; in biology, the concept of the variable camber airfoil can be employed to explain the mystery of animal flight. In the case of low-speed aircraft, the performance of...

New research from Lund University in Sweden reveals the value of carrying two layers of wings around. The researchers studied dung beetles and the way their protective forewings actually function. These wings do not only protect but also help the beetles to lift off from the ground — albeit at a cost. The forewings of beetles, the elytra, are hardened structures which protect the insect's flying wings and body. The function of the forewings in flight has been questioned, which is...

The companies anticipate signing a definitive agreement to formalize this project by June 4, 2012. This MOU serves as an important step in establishing...

Bats Save Energy By Drawing In Wings On Upstroke

[ Watch the Video ] Whether people are building a flying machine or nature is evolving one, there is pressure to optimize efficiency. A new analysis by biologists, physicists, and engineers at Brown University reveals the subtle but important degree to which that pressure has literally shaped the flapping wings of bats. The team's observations and calculations show that by flexing their wings inward to their bodies on the upstroke, bats use only 65 percent of the inertial energy they...

Model gives clues on how to optimize homogeneous feeding of cells in suspension from a liquid nutriments supply in a bioreactor Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about to be published in EPJ E´, was performed by Jorge Peixinho from CNRS at Le Havre University, France, and his colleagues from the Benjamin...

The boomerang is a flying tool, made of wood or carbon fiber-reinforced plastic, with a curved shape that is often used as a weapon or for sport. They have also been made of bones and come in many different shapes and sizes depending on their geographic or tribal origins and their intended function. The most commonly recognizable type is the returning boomerang which travels in an elliptical path and returns to its point of origin. The returning boomerang has lopsided wings in order to create...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...
