Basis of high-pressure water-ice jet creation and application for surface treatment

摘要

The high-pressure water-ice jet treatment is a new technology that has grown in popularity lately. The presented technology is based on a high-pressure water-ice jet with addition of dry-ice CO_2 pellets. The theoretical basis, including velocity and kinetic energy distributions of ice particles also with thermodynamical particle states during the water-ice jet creation are discussed. Using theoretical results the experimental plant, accompanied with suitable equipment, was built. It enables adequate research to be achieved that makes it possible to determine the jet erosion mechanism and point out the effects of different material treatments.
