Abstract

Study is reported of the cavitation erosion behind blunt bodies with varying hydrodynamic factors of flow, such as test time, cavity length, velocity, pressure; the geometrical parameters of the system such as the size and shape of the cavitating body, its aspect ratio, and surface roughness; and the mech. properties of the materials such as d., yield strength, tensile strength, engineering strain energy, hardness, ultimate resilience, percent elongation, percent redn. in area, and elastic modulus. A study of the vol. eroded along with the hydrodynamic flow factors and the system geometrical parameters in general indicated that corrosion is very severe in a crit. zone of cavitation. This crit. zone is described by a range of values of V/l (where V = velocity of flow and l = length of the cavity). Among the correlations studied for the inverse rate of vol. eroded as a function of individual and twin mech. properties, the product of ultimate resilience and Brinell hardness showed the best correlation. 35 refs.
