The Experience of Non-Stationary Flow Visualization Using the Hydrogen Bubble Method

The study of the spectra of flow is carried out by experimental methods. The paper summarizes the authors’ experience in the design, construction and use of hydrodynamic installations for the visualization of liquid or gas flow using hydrogen bubbles obtained by electrolysis of water. The design of a vertical hydrodynamic pipe, the technology of making experimental models, the design and purpose of the main equipment are considered. Research methods and procedures are described. The article presents the results of the studies that make it possible to evaluate the capabilities of the experimental equipment and picture physical processes around the bodies that change the kinematic parameters of motion in the incident flow according to a given law. The proposed research methods and experimental equipment are distinguished by originality. They can be used to study the features of macrostructures around bodies of complex geometric shapes and laws of motion.
