Informatics of optoelectronic measurements: Science and innovative industrial technologies

Development of the method of laser Doppler anemometry for diagnostics of turbulent flows at high speed

“…The LDA method does not disturb the flow and has a small measurement error. Measurement of the kinematic parameters of turbulent flows at a high speed is a difficult task [1].…”

Optoelectronic Measurements in Science and Innovative Industrial Technologies

“…This experimental specimen for works in real field conditions was created in half a year. In the industrial tests at the Kalchinsky oilfield, it was found that the experimental information-measurement complex for multiphase borehole flow meter survey at boreholes 300/7 and 301/7 successfully operated uninterruptedly during five days at environmental temperatures from -36°C to -10°C, providing real-time measurements of the borehole fluid flow rate with a measurement error of 3% (Meledin, 2008(Meledin, , 2009). …”

“…Now, a simplified variant of the complex (without dynamic models and virtual systems of coordinates, only local measurements are made) is widely used on the Russian railroads. At present, more than 38 large Russian railro a d s t a t i o n s h a v e b e e n p r o v i d e d w i t h a measurement system of the Complex type (Meledin, 2008(Meledin, , 2009). …”

“…This method is simple and inexpensive. It can serve as a basis for a wide range of applications in atomic and other industries where precision size control in a range limited only by the sizes of the scanner used is required (Meledin, 2008(Meledin, , 2009). …”

“…Recently, of special importance are code verification in Computational Fluid Dynamics (CFD) and computer models of flows in science and innovative industrial technologies. Such laser information systems, which are highly competitive with the best foreign analogs, simple and safe, are also necessary for educational purposes (Meledin, 2009). This high level of achievements is based on a series of papers, published in the 80s and 90s, on the creation of systems based on gas lasers and development of the first injection laser emitters for optical instrument making -jointly with Ioffe Physico-Technical Institute, RAS, and under the guidance of Zh.I.…”
