โฆ Synopsis
The effects of local variations in interfacial tension on the motion of drops in liquid-liquid systems are discussed. Experimental observations of the various types of motion which are caused by the addition of solute to the dispersed phase are described. Approximate models of the drop motion are used to make quantitative estimates of the relative importance of different dynamical modes in dissipating the surface energy. Values of the parameters which characterize the transient behaviohr of the oscillation mode are estimated and compared with observed values.

The flow ofnon-Newtonian purely viscous fluids through packed beds of different structures has been investigated and a model of calculation of the pressure drop is proposed. This model takes into account the structural parameters of the porous medium: the tortuosity T, the dynamic specific surface a
Drops formed at a tip which exhibited damped oscillatory behavior when re.leased were observed and frequencies compared well with the theory of Miller and Striven. The observed damping factors were considerably higher than predicted by the same theory, possibly because of the presence of trace conta
