THE INSTALLATION FOR THE RESEARCH OF CAVITATION PROCESSES IN COOLING SYSTEMS OF MARINE DIESEL ENGINES

Abstract

The article describes the design of the experimental installation that provides new data on cavitation-erosion failures in high-temperature cooling systems. Based on the analysis of domestic and foreign sources of scientific and technical information concerning the research of cavitation processes, technical objects where cavitation processes take place, factors that affect the intensity of cavitation-corrosion destruction, and methods that are used for cavitation research are identified. A modernized design of the laboratory unit is proposed. The main element of it is a high-frequency magnetostrictive vibrator. Due to the sealed experimental cavity, the unit allows the determining of the intensity of cavitation-erosion destruction at high liquid temperatures and pressure above atmospheric, which is typical for high-temperature cooling of marine diesels. The usage of the installation will allow getting the correct data about the resource of elements of high-temperature cooling systems for marine diesels.
