Investigation of the Jet Liquid Flows Structure by Multicolor Particle Image Velocimetry

The work aims investigating the application aspects of multicolor particle image velocimetry for the diagnosis of jet liquid flows. The main feature of the method proposed in this work compared to particle image velocimetry is the radiation probing with three laser planes of different wavelengths located at a short distance from each other. This modification allows obtaining information about the flow structure simultaneously in three different planes. A jet liquid stream from a sprayer has been considered as a research object. As a result, a laboratory setup was assembled and a series of experiments were carried out. The paper presents examples of experimental images, the processing result, describes its algorithm, and also estimates the accuracy of the data obtained. © 2021 National Research Nuclear University.
