摘要: A unique, actively controlled pumping system allows independent control of inflow and impeller perturbations, as well the phase shift between them. The basic configurations an impeller-diffuser blade have been investigated, with objective manipulating spectral content unsteadiness near-wave at discharge. Substantial alteration discrete components can be attained. central feature is generation a number nonlinear interaction components, corresponding to sum difference frequencies, forcing- passing-frequencies their harmonics
