Abstract

Measuring the properties of multiphase fluids using the BEM A. A. Mammoli Department of Mechanical Engineering, University of New Mexico, USA Abstract Measurement of the constitutive behavior of multiphase fluids is one of the most interesting and difficult problems in rheology. The Boundary Element Method is particularly suited to modeling the flow of such fluids because of the relative ease of accurately representing their complex geometry without excessive meshing dif- ficulties. Many papers have been published on the subject, but to the author's knowledge, the literature on the actual implementation of such methods is scarce. Here, a parallel implementation of a code based on the completed double layer boundary integral equation, with Barnes-Hut multipole acceleration, is described briefly. After determining the level of mesh refinement required to obtain conver- gent results, the code is used to predict the rheological behavior of suspensions of rigid particles of different
