USING CAVITATION SELF-OSCILLATIONS TO GENERATE PERIODIC PULSED JETS

  • Published:
Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

The possibility of using fluid jet flows in the presence of an artificial cavity with a negative cavitation number to generate periodic pulsed jets is studied. Flow in a line consisting of a cavitator, an artificial gas cavity, and a converging nozzle through which liquid and gas flow into the atmosphere is investigated. Regimes in which the liquid exit flow is close to intermittent are experimentally found. For such flow regimes, a one-dimensional model for estimating the flow rate of liquid portions from the nozzle is proposed.
