STUDIES OF COALESCENCE OF BUBBLE PAIRS

The coalescence behaviour of bubble pairs formed on two adjacent capillary tubes was studied in aqueous solutions of n-alcohols and fatty acids at various concentrations. Coalescence frequency and coalescence time were measured. The results show that coalescence time seems to be the best physical ma...

description The coalescence behaviour of bubble pairs formed on two adjacent capillary tubes was studied in aqueous solutions of n-alcohols and fatty acids at various concentrations. Coalescence frequency and coalescence time were measured. The results show that coalescence time seems to be the best physical magnitude which can describe the coalescence process, because bubble coalesce only if the contact time of the bubbles is greater than the coalescence time. The coalescence time in solutions is proportional to the surface excess concentration of the solute. Coalescence time increases with the polarity of the hydrophylic group and its chain length and decreases with decreasing bubble size and increasing temperature.
