The present invention sets formula (1) for calculating an estimated cavitation jet performance (E). On the basis of data pertaining to a jet pressure (p1), a nozzle diameter (d) and a cavitation number (sigma), and data pertaining to a cavitation jet performance (ERmax) for such data, the present invention specifies, in formula (1), the power index n(sigma) of the term Xn(sigma) pertaining to the power law of the jet pressure (p1) of the cavitation jet, and the power index m(sigma) of the term Ym(sigma) pertaining to the power law of the nozzle diameter (d) generating the cavitation jet. The present invention finds the estimated cavitation jet performance (E) using the above data pertaining to the jet pressure (p1), the nozzle diameter (d) and the cavitation number (sigma), as well as formula (1) and the functions n(sigma) and m(sigma) for the specified power indices. |
