    Abstract

    Experimental investigations made on the characteristics of erosion resulting from the impingement of liquid jets is reported. Experiments were conducted for several plain jets of 4- to 12-mm diameter and jets with cavitation inducers of four diameter ratios in a velocity range of 5 to 45 m/s. A detailed dimensional analysis of the several parameters governing liquid impingement erosion is presented. The erosion rate-time curves for impingement by jets with cavitation inducers did not show the incubation and accumulation zones significantly. The normalized erosion rate increased with jet velocity and approached a constant value at higher jet velocities. The erosion rate decreased rapidly and then remained approximately constant with an increase in caviation number. The erosion rate increased faster with frequency of impingement than with increase in jet velocity. A maximum value in peak erosion rate occurred around angles of impingement of 25 to 40 deg.
