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.

建议编号：CTS-0218801首席研究员：C.Pozrikisis研究所：加州大学圣迭戈分校标题：颗粒、液滴和胶囊悬浮液的流体动力学研究拟议项目的目标是通过将边界积分法与有限差分技术“杂交”来显著提高边界积分法的有效性。其目的是能够对流体中悬浮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。该方法的创新之处在于将边界上的点力分布投影到底层配置点上，并在该网格上求解流场。该方法将应用于悬浮液、含和不含表面活性剂的乳剂、胶囊和泡沫。该方法在大型并行处理机上是可扩展的。
