Implication

Laboratory experiment demonstrates temperature-dependent rise velocity shifts between oscillating and nonoscillating clean bubbles, highlighting hydrodynamic transition thresholds.

Key Points

To measure and model how temperature and equivalent spherical radius influence the terminal rise velocity and oscillatory behavior of single clean bubbles.
Conducted microphysical laboratory experiments evaluating single clean bubbles with equivalent spherical radii ranging from 377 to 4500 μm.
Tested hydrodynamic behaviors across a controlled liquid temperature range between 0°C and 40°C.
Formulated a three-part empirical parameterization for rise velocity using experimental and published literature data, segmented by Reynolds number (Re = 1) and the onset of trajectory oscillations.
Rise velocity increased with temperature for nonoscillating bubbles but decreased with temperature for oscillating bubbles as trajectory oscillations intensified.
The critical transition temperature governing the shift from steady to oscillatory motion scaled linearly with bubble radius.
The resulting empirical parameterization accurately describes rise velocity across both oscillatory and nonoscillatory regimes as a function of bubble radius and temperature.
