  • Descrição: In the present work some aspects of cavitation influence on the European Spallation Source (ESS) liquid metal target are investigated. The analysis is based on a calculation of the bubbles' radius change for bubbles moving along a changing pressure field. The shape of pressure field is obtained from numerical investigation of fluid flow in the ESS model. A simplified pressure model is used to find how a bubble's radius depends on pressure and temperature. The main goal of this work is to determine conditions (such as bubble initial radius, temperature, pressure) leading to bubble's growth or collapse. In all cases "stability" curves (curves dividing area of bubble growth from area of bubble collapse in dependence of some parameters) are constructed.
