Modeling of gas bubble dynamics in liquid media under Doppler effect of ultrasound radiation

Abstract

The dynamics of gas bubbles having different sizes was modeled for liquid media under the influence of ultrasound radiation in duplex research mode based on radiation pressure forces. Factors were considered and conditions were evaluated for occurrence of the “pseudo-flow” artifact in liquids with gas bubbles having different sizes under different radiation modes, intensity levels and work frequencies of ultrasound sensors for media with different viscoelastic behavior.
