This volume covers the traditional aspects of both water and fluid jets, including fluid mechanics, cutting and drilling, abrasive jets, pulse jets, jet manipulation, jet/target interaction, nozzle systems, pumps and intensifiers, surface treatment and cleaning. These techniques have a wide application in a number of different areas, including aerospace, civil engineering, manufacturing, mining and medicine. Among the other issues covered are application opportunities, user requirements, codes of practice, legislation and safety.
BHR GROUP LIMITED is an independent Contract Research and Technology organization, whose services to Industry are centred around core skills in fluid engineering, and include contract research and development, consultancy, software design and development, and conferences. BHR Group's annual programme of international conferences, seminars and courses provides a forum to address the demands of a changing market and explore the requirements for advances in technology and the application of existing technologies.
