VORTEX CHAMBER FLOW DIAGNOSTICS DEVICE Russian patent published in 2024 - IPC G01P5/26 

FIELD: measurement.

SUBSTANCE: use for diagnostics of flow in vortex chamber. Essence of the invention consists in the fact that a device for diagnosing flow in a vortex chamber, based on digital particle image velocimetry (PIV), includes a vessel for working fluid, including tracer particles, a pump, a flow meter, a vortex chamber with tangential nozzles to create a swirled flow in the vortex chamber, a pulsed laser, optics for creating a laser knife, a chamber for detecting scattered radiation, a PIV analyser, pressure sensors on the inner walls of the vortex chamber, a pressure signal processing unit, wherein the pressure signal processing unit measures the pressure signal periodicity, and the PIV analyser averages the velocity fields according to the measured pressure signal periodicity.

EFFECT: providing the possibility of increasing the signal-to-noise ratio and visualizing the vortex flow pattern.
