METHOD OF LIMITED (CLOSED) NON-STATIONARY EDDY CURRENTS IMAGING Russian patent published in 2016 - IPC G01P5/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to instrumentation equipment and allows to study limited (closed) vortex flows of liquid. Invention can be used in fundamental and applied studies in experimental hydrodynamics. Application in ecology, processes of chemical and catalytic reactions, studying atmospheric phenomena is possible, as well as in some other areas of science and industrial technologies related to need in non-disturbing measurements and control. Method of closed non-stationary eddy currents imaging involves, that after establishing analyzed flow conditions through hole in lower fixed cover enclosed volume near-bottom area with working fluid is filled with dye. At that, coloring agent is used with density in 1.2-1.4 times exceeding working fluid density. At that, during visualization dye density is reduced, and dye dissolution time is more than flow imaging characteristic time.

EFFECT: technical result is enabling research of closed non-stationary eddy currents with Re of more than 6,000.
