Drag of a growing bubble at rectilinear accelerated ascension


The problem of predicting the drag coefficient of a growing bubble at rectilinear accelerated ascension in uniformly superheated pure liquids and in binary solutions with a nonvolatile solute at large Reynolds and Peclet numbers is discussed. In the case of pure liquids, the general solution for the drag coefficient of an accelerated growing bubble from its inception at the critical radius and through the surfacetension, inertia, and heatdiffusioncontrolled regimes is established, as well as some necessary adaptations in the case of binary solutions with a nonvolatile solute. Two particular limiting regimes in the case of pure liquids, inertiacontrolled and heatdiffusioncontrolled regimes, respectively, are analyzed in details, with satisfactory results.
