A note on single bubble motion in surfactant solutions

This note addresses measurement of single bubble velocity in surfactant solutions and the physical model of the effect of surfactant concentration on the steady-state velocity. Continuous tracking of the bubble along the rise path is used as the measurement method. Using this technique, the steady-s...

Summary:This note addresses measurement of single bubble velocity in surfactant solutions and the physical model of the effect of surfactant concentration on the steady-state velocity. Continuous tracking of the bubble along the rise path is used as the measurement method. Using this technique, the steady-state velocity is found to be independent of surfactant concentration over a wide range, which contradicts the data frequently used to develop models.
