Ultra-wet Gas Turbine

07.06.2012
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: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
