| Abstract;In order to clarify the practical cleaning action on a working surface resulting from impinging water jets for wash jet nozzles, by means of a pressure sensitive film technique and an image processing method, we measured distributions of impact pressures on flat plates against the impinging jets induced by a solid jet nozzle and a flat one for several standoff distances and impinging angles. Next, we removed organisms attached to marine floats, PVC plates, and steel pipes using these nozzles with several impinging angles. Results indicated that an impinging angle of about 60.DEG. facilitated efficient cleaning of the attached marine organisms. Characteristics of those distributions differed greatly for the solid jet nozzle and the flat one, furthermore, impact pressure for the solid jet nozzle was larger than for the flat one.
