Innovative Profile Sensor for Measuring Turbulence


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: 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...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
