On the threshold of 1/2 order subharmonic emissions in the oscillations of ultrasonically excited bubbles
A. J. Sojahrood, N. R. Shirazi, H. Haghi +2
The pressure threshold for 1/2 order subharmonic (SH) emissions and period doubling during the oscillations of ultrasonically excited bubbles is thought to be minimum when the bubb…

Classification of the mechanisms of wave energy dissipation in the nonlinear oscillations of coated and uncoated bubbles
A. J. Sojahrood, H. Haghi, N. R. Shirazi +2
Acoustic waves are dissipated when they pass through bubbly media. Dissipation by bubbles takes place through thermal damping (Td), radiation damping (Rd) and damping due to the fr…
