Abstract

The dimensional influence of bodies on their cavitational characteristics is well known. There are normally smoothly varying functions of dimensions D or Reynolds numbers Re obtained with their use, so the extrapolation of laboratory measurements to larger scales is based on this smoothness. But sometimes experimental data cannot be described by mono tonic functions (Arakeri & Acosta [1]) or unbroken curves (McCormic [ 2], Fruman et al. [3]) and the extrapolation of these data without an additional theoretic analysis is quite risky. As a result of such an analysis it is shown here that those anomalies of dependences of cavitation inception number Keywords
