ABSTRACT
Since 1986 a physical modelling of various aspects of high-pressure water jet behaviour and jet – material interaction has been performed in the High pressure water jet laboratory of the Mining Institute of the Czechoslovak Academy of Sciences. After creating a new physical model of jet – material interaction, completed last year, a study of the interaction between jet and abrasive particles in the mixing chamber was begun. Several physical models describing the processes taking place during jet – abrasive interaction have been prepared and tested. Based on these models the mathematical description has been prepared to study abrasive particle deformations and failures. A theoretical base and first numerical experiments are described and discussed in this article.
