提案编号： CTS-0218801主要研究者：C. Pozrikidis机构： U加州，圣地亚哥标题： 研究颗粒、液滴和液体的悬浮液的流体动力学， capsulesABSTRACTThe拟议项目的目标是显着提高边界积分法的有效性，通过“杂交”它与有限差分技术。其目的是能够进行数值模拟与许多颗粒悬浮在流体中的目的是研究液滴，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基本的配置点上，并在此网格上求解流场。 该方法将适用于悬浮液，乳液与表面活性剂，胶囊和泡沫。 该方法被证明是可扩展的大型并行处理器上。

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.
