摘要

Equation (1) for calculating estimated cavitating jet performance E is set, a power index n(σ) of a term x^n(σ)relating to a power law of an injection pressure p₁of a cavitating jet and a power index m(σ) of a term y^m(σ)relating to a power law of a nozzle diameter d for producing the cavitating jet in Equation (1) are specified from data on the injection pressure p₁, the nozzle diameter d and a cavitation number σ and data on cavitating jet performance E_Rmaxcorresponding to these pieces of data, and the estimated cavitating jet performance E is obtained using the data on the injection pressure p₁, the nozzle diameter d and the cavitation number σ, the Equation (1) and the functions n(σ), m(σ) for the specified power indices.
