This paper presents a three-dimensional simulation of cavitation bubbles cloud effects on accessories and elements of compressor refrigerating installation, intermediate heat exchanger, as well as pumps and pumping stations. Bubbles appear on sections of these units due to fluid movement. Simulation has demonstrated high dependency of cavitation effects on a cavity shape. Thus, structural solutions subjected to change shapes of cavity can allow minimal cavitation effects on accessories, and elements of hydraulic equipment.
