Ultra-wet Gas Turbine

We offer a method to improve the passive scalar homogenization of mixing fluidic jets in cross flow configurations especially within the combustion chamber of a turbine. This is achieved by using fluidic oscillators that create an oscillating or pulsating fluid flow at the oscillator exit due to their way of construction. By this improved method high amounts of steam can be added to the combustion process and thus significantly increase the level of efficiency.<<br><br>The oscillation frequency of the injected fuel is thereby regulated only by the mass feed of the supplied fluid.<br>

The combination of cross flow injection and oscillation/pulsation of the fluid flow increases primarily the mixing ration of the two fluid flows within a combustion chamber (fluid & air) and moreover leads to a more effective burning. <br> The fluidic actuators can be installed within new (gas) turbines but can also be integrated in already existing ones.<br> <br> <strong>Benefits</strong><br>

<ul> <li>Better temporal homogenization: NOx reduction, improved fuel value</li> <li>Pressure loss in turbine is reduced: enhancing performance rate</li> <li>Decrease of mixing length by ca. 50%: turbines could be build smaller</li> <li>Fluidic oscillators require less maintenance</li> <li>Usage of nearly any gaseous fuels</li> <li>Increased macro- and micromixing phenomena: higher gains in mixing quality</li> </ul> <strong>IP Rights</strong><br> PCT application filed<br> <br> <strong>Patent Owner</strong><br> Technische Universität Berlin</p>

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
