environmental constraints on the emission of particulate matter into the air during abrasive blast cleaning of steel structures prompted an investigation in to the use of cavitating water jets to propare surfaces prior to repainting. several cavitating water jet nozzles were lab tested to determine their area cleaning rate, effectiveness and thrust index in the removal of paint systems from test panels to an acceptable cleaned surface. the lab results indicated that the cavijet 0.073 organ pipe nozzle had the highest rate of cleaning. the cavijet 0.050 fanjet was the most effective cleaning nozzle and had a lower thrust value. this program included the design and fabrication of four hand-held tools that would utilize optimum cavitating nozzles; determined by lab work
