The subject is aimed at transfer of knowledge of physical processes taking place during interaction of liquid jet with matter, according to its state. The main emphasis is put on understanding of different interaction effects of liquid jet according to its actual character (pure liquid, liquid with liquid additives – polymers, liquid with solid state admixtures – abrasives, liquid in unusual thermodynamic states – supercooled or overheated) on matter in a solid state. Particular emphasis is put on differences in physical processes regarding the structure of the solid state matter and its thermodynamic state. The subject is based on extensive experimental background of own laboratories and practical experience.
