PROCEDURES AND PREPARATION FOR THE PRODUCTION OF A FLIGHT STRAIN FOR A MATERIAL PROCESSING

摘要

The fluid jet (5) passes through a fluid nozzle (1), then through a gas outlet nozzle (23) which is remote from it (1). The gas outlet nozzle forms a gas jet which surrounds the fluid jet and acts upon it. Within a given tolerance, axes of the fluid and gas jets coincide. Kinematic viscosity of the gas is less than that of the atmosphere. Independent claims are included for the equipment and fluid nozzle.
