ABSTRACT:
This invention relates to an injector in which fluid is injected into a reaction region 30 after pressurization and translation in traveling cells 20 between crests 46 of traveling waves of one or more waveplates 12 made of shear transducer material. Multiple phases of applied electrical stimulation cause electrical segments of the waveplate to form traveling waves by shearing in a predetermined sequence of amplitudes. Inlet wave amplitude taper 14 provides a prescribed state of inlet fluid acceleration. Outlet wave amplitude taper 18 predetermines the degree of mixing of two or more exiting fluids. Self filtering, valve action, high pressure, and high mass flow are provided with few and relatively benign modes of apparatus degradation due to friction. High system efficiency results from absence of rubbing and the recirculation of stored energy. The fluid delivery rate is smooth, continuous, and electrically variable. Balance of the mass flow rate of two or more fluids is electrically controlled.
