On the Earnshaw and the Van den Tempel-Lucassen Compositional Viscoelastic Theories

We consider a diffusion-controlled solute transfer and discuss the reasons to study the complete convective-diffusive equation to determine the coupling resonant domain between capillary and longitudinal waves in terms of viscoelastic compositional behavior. A perturbation of the surface tension due to solute transfer has two contributions. One is proportional to the surface area change while the other, not considered in the Van den Tempel-Lucassen theory, is due to the surface velocity. Copyright 2000 Academic Press.
