Sonic Cavitation in Water
Abstract
Nearly four years of experiments in treating water to retard the onset of cavitation resulting from high-intensity acoustic waves is described. Sound intensity 23 times that at which cavitation occurs in pure (deionized) water can be applied to specially treated water without causing cavitation. The three effective methods examined are unusual in that the water is 'strengthened' by additives that: (1) remove nuclei by deoxygenation; (2) increase molecular bonding by hydrogenation; or (3) augment cohesion by introducing a natural polymer. An appended survey of the literature documents the complexity of water and serves as an excuse for omitting a hypothesis to explain the increased resistance to cavitation that results from the treatments.
