ACOUSTIC CAVITATION IN FLUIDS

机译:流体中的声空化

摘要

in various implementations, a field-deployable system may include an array of two or more acoustic transducers arranged to propagate pressure waves through a hydrocarbon fluid medium. A method of stimulating a hydrocarbon fluid medium may include propagating pressure waves through the hydrocarbon fluid medium. The pressure waves may have an ultrasonic frequency and an amplitude sufficient to induce acoustic cavitation in the hydrocarbon fluid medium. A method of stimulating a solvent fluid medium may include propagating pressure waves through the solvent fluid medium, and inducing acoustic cavitation in the medium via the pressure waves. The acoustic cavitation may form a microjet that impinges a proximate solid surface to substantially remove hydrocarbon residue. An acoustic transducer may be configured to propagate pressure waves through a hydrocarbon fluid medium. The pressure waves may have an ultrasonic frequency and an amplitude sufficient to induce acoustic cavitation in the hydrocarbon fluid medium.
