Experimental research of cavitation in channels of very small scales

Abstract

This paper deals with defining of experimental methods and with description of an experimental setup used in research of fluid flows in jets and other orifices of very small scales. The jet used in the experiments has an axissymetric shape with circular cross-section. The experimental setup used for experiments consists of these basic parts: a device used for microscopic visualization and capturing of image of the liquid flow in small scale channels, a digital image data acquisition system and a system of image data manipulation, a system for parallel acquisition and manipulation with other experimental data.
