Abstracts:
This paper considers the improvement of existing and development of new approaches to the treatment of experimentally obtained data by particle tracking velocimetry. The approach can be applied in practice to solve current scientific and applied problems in fluid mechanics and gas, energy, transportation systems, etc. Moreover experimental research data as isothermal turbulent jets formed ramjet nozzle diameter of 15 mm at flow mode Re = 6000 were processed by the algorithm. A distinctive feature of the experiment is using a high-speed shooting 770 Hz instead of 10 Hz, which is technically more difficult to realize |
