项目编号：cts -0218801项目负责人：C. pozrikidis机构：U California， San diego gotle：颗粒、液滴和胶囊悬浮液的流体动力学研究摘要本课题旨在通过将边界积分方法与有限差分技术“杂交”，显著提高边界积分方法的有效性。其目的是能够对悬浮在流体中的许多颗粒进行数值模拟，目的是研究液滴、胶囊和颗粒的流动特性。该方法的新颖之处在于将边界上的点力分布投影到一个底层的配点上，并在网格上求解流场。该方法适用于有或没有表面活性剂的悬浮液、乳剂、胶囊和泡沫。该方法在大型并行处理器上具有可扩展性。

Proposal Number: CTS-0218801Principal Investigator: C. PozrikidisInstitution: U California, San DiegoTitle: Investigation of hydrodynamics of suspensions of particles, droplets, and capsulesABSTRACTThe objective of the proposed project is to significantly improve the effectiveness of the boundary integral method by "hybridizing" it with a finite-difference technique. The purpose is to be able to carry out numerical simulations with many particles suspended in a fluid with the objective to study flow characteristics of drops, capsules, and particles. The novel aspect of the approach is to project the point force distribution on the boundary on an underlying collocation points and solve for the flow field on this grid. The method will be applied to suspensions, emulsions with and without surfactants, capsules, and foams. The method is shown to be scalable on large parallel processors.
