Abstract: An asymptotic analysis with the method of multiple-parameter perturbations has been carried out to examine the basic features of drop oscillations in a uniform flow field. The quiescent drop shape has an oblate deformation ...

Abstract: A previously unreported feature of the coalescence of water drops was observed for an isolated pair of drops (R = 275 ?m and r = 200 ?m) falling at terminal velocity through nearly saturated air. This new feature, grazing ...

Abstract: A perturbation model for the shape of falling drops in the presence of electric fields and charges was developed by extension of previous methods that includes aerodynamic effects in the pressure balance equation of Laplace. ...
