Innovative Profile Sensor for Measuring Turbulence

07.02.2005


In order to carry out research on complex flow processes, the Laser Zentrum Hannover e.V. (LZH) has developed a special sensor that can be used to measure turbulent jet flows.



Turbulence is one of the last phenomena in the field of physics which has is still not understood. However, the rapid development of computer simulations and experimental technology has led to a better understanding turbulence. Phenomena like reducing the turbulence of ships by using micro-bubbles, or increasing the flow rate in pipelines by adding polymers are beneficial, but still not understood completely.

At the LZH, an innovative profile sensor is being developed, which can be used to determine the velocity profile of turbulent shear flows, with high spatial and temporal resolutions. The profile measurements can, for example, provide information on spatial-temporal correlations in turbulent flows. Furthermore, the sensor can be used for a number of technical applications such as flow measurements in high-pressure gas or oil pipelines, or for flow measurements for fuel injection nozzles, on airfoils and aircraft surfaces, or in aircraft turbo-engines.


The research work is in cooperation with the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig (Dr. H. Müller), and is supported by the Deutsche Forschungsgemeinschaft (DFG).

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Computer-assisted methods aid Heidelberg physicists in reproducing experiment with ultracold atoms

Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
