.... As an application of the present theory to an inducer representing an axial pump or compressor, the number (N cav ) of “backflow-vortex cavitations,” which occur around the backflow-vortex center, is predicted. Cavitation is visible; therefore, N cav is quantitatively measurable. In the parameter ranges studied...
