Description
Summary:The paper reports about investigations into the removal of thick organic protective coatings with rotating high-speed water jets. Ten nozzle carriers, rotating at a very high speed of 3000 min 1 , were applied at stand-off distances between 10 and 82 mm. Widths of the eroded sections and the percentage of completely exposed steel sections were estimated. Color-based image processing was applied for the assessment of exposed steel sections. The results reveal two types of performance. (i) Carriers with a moderate number of nozzles travelling on more than one orbit exhibit a maximum performance at characteristic optimum stand-off distances. (ii) Carriers with nozzles travelling on one orbit perform best at the lowest stand-off distance; these configurations generate notable swirl pattern (lack of overlap) in the center of the erosion path. The most effective configuration is characterized through an optimum balance between nozzle number, nozzle diameter, and nozzle orbit for a given stand-off distance.
