Description
  • An experimental study has been aimed at examining the coalescence phenomena in aqueous solutions of aliphatic alcohols and electrolytes and at determining the efect of these surface-active compounds on bubble coalescence in viscous aqueous media with Newtonian and non-Newtonian behaviour, represented by aqueous solutions of 50 and 60 wt%, saccharose, and 0.2 and 0.5 wt%, xanthan, respectively. Bubble coalescence in aqueous solutions of alcohols and electrolytes was significantly hindered by increasing solute concentration and the coalescence percentage t exhibited sharp transition from 100% of bubble pairs coalescing to very low values over a narrow concentration range. Transition concentrations of respective surface-active additives, characterizing suppression of coalescence in their aqueous solutions, were successfully correlated as a function of the surface tension gradient, with exponent values 1/3 and 1/4 (or 1/6) for solutions of alcohols and electrolytes, respectively. The inhibitory effect of
