Underwater processing is a growing field of application for plasma technologies, e.g. for repair work at marine and off shore installations. Underwater plasma activities range from welding, powder densification, cutting, hardening, surface evaporation to thermal spraying. In order to enhance these technologies, numerous experiments for each new application have to be undertaken so far, usually conducted in a trial and error approach. Since the number of parameters is high, the knowledge of these processes at atmospheric pressure is only partly usable and measurements are difficult to conduct under water, new methods of investigating these systems are required. A thorough systems analysis and a verified numerical model provide a scientific basis for areas of detailed experiments and research. In this paper, results of a modelling and simulation approach for investigating underwater plasma jets for spraying are presented, showing good agreement with experimental findings.
