The Novosibirsk researchers have developed a device capable of producing mist with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The precise name of the device is “field device for measuring liquid and gas velocities”. It helps to perform prompt, precise and, most importantly, simultaneous measuring of the velocity at any point of the fluid and gas flow.
“Field device for measuring liquid and gas velocity” is the name of the device developed and produced by the researchers of Institute of Thermal Physics, Siberian Branch, Russian Academy of Sciences (Novosibirsk) with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The device helps to track in full detail the life of the flow and to learn, for example, what the velocity is at each point, how and where turbulences appear. In other words, it is possible not only to “shoot an animated film” about the flow of liquid or gas, but also to perform mathematical treatment of each “shot”.
The device operations are based on the principle known since the times of Prandtl and other classical hydrodynamics scholars. This is the so-called stroboscopical visualization of flows. In other words, small particles – tracers – are placed in the flow transparent for employed irradiation. The tracers do not influence the stream, they drift together with the flow, but the tracers are not transparent for irradiation.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
