Effects of gravity level on bubble detachment, rise, and bouncing with a free surface
International Journal of Multiphase Flow(2019)
摘要
•Bubble terminal velocity increases with the gravity level, although bubbles are smaller at higher values of gravity.•The bouncing process has been modelled by a damped oscillator, in which the free surface acts as an elastic membrane.•The frequency of bouncing increases with gravity, in accordance with the theoretical model.•Viscosity is not the main responsible for damping in the bouncing process.
