Abstract

In order to clarify curvature effects upon the peening action on a working surface resuling from impinging high-speed submerged waterjets, we systematically investigate the spatial distributions of the impulsive pressures induced by cavitation for several convex-and concave-cylindrical surfaces with various curvatures, by means of a pressure sensitive film technique which can detect the spatial distributions easily. The distributions do not appreciably change with the curvature, except for the case when the cylinder diameter is less than the jetwidth. Expectedly, the impulsive pressures develop almost uniformly as far as the rear convex surface, even for a slender cylinder.
