Abstract

Approximation of multicornponent fluid flows with a varying coefficient of interfacial tension W.W. Miles Department of Mathematics and Compzrter Science, Stetson Universip, USA Abstract This work investigates the modeling of multicomponent, viscoelastic fluid flows. The governing equations are presented as well as results pertaining to the existence and accuracy of the solution to the approxin~ating system of equations. The set of governing equations includes the imposition of a "jump" condition which exists at a fluid-fluid interface. The Interfacial tension forces which act along the interface are transformed into volumetric forces via a method similar to the continuous surfaceforce model of Brackbill, et. al. [I]. In multicomponent fluid flows, the interfacial tension forces may play a significant role in morphological development. Higher values of the coeficient of interjkial tension a allow for less deformation of the minor phase while lower values of o allow the minor phase to udergo la
