CTS-9817633C. Pozrikidis, UCSDAn advanced boundary element integral method is proposed to investigated rheology of deformable liquid drops and elastic capsules in homogeneous and bounded flows at very low Reynolds numbers (Stokes flows). Development and implementation of numerical methods for accurate tracking of two- and three-dimensional interfaces are proposed. Several case studies are considered including suspension flow of liquid drops in channels, of liquid drops in homogeneous shear flow in the presence of surfactants, and of elastic capsules in homogeneous shear flow and channels. If successful, the results will contribute to the advancement of basic understanding and prediction of suspension flows with deformable dispersed phases, with potential relevance to industrial, natural and physiological processes.

CTS-9817633C。Pozrikidis，UCSD提出了一种先进的边界元积分方法来研究变形液滴和弹性胶囊在非常低的雷诺数下的均匀和有界流动（Stokes流动）中的流变学。 提出了精确跟踪二维和三维界面的数值方法的开发和实施。 几个案例研究被认为是包括悬浮液流的液滴在通道中，在表面活性剂的存在下，在均匀剪切流的液滴，和弹性胶囊在均匀剪切流和通道。 如果成功的话，结果将有助于推进基本的理解和预测悬浮液流与可变形的分散相，与工业，自然和生理过程的潜在相关性。
