This paper is concerned with cavitation and erosion in submerged water jet. Impulse force generated by cavitation bubbles in the jet is measured by an impulse force gauge. The accumulated count of impulse force per unit time is shown against the impulse force and the standoff distance from the nozzle exit. It is found that there are maxima in impulse force at two different standoff distances of 30 and 80, which are the values normalized by the nozzle diameter (=1. 5 mm), and that the impulse force mainly appears in frequencies of a few Hz. Laser-microscopic observations show that erosion patterns on aluminum surfaces are classified into two ones.
