AbstractCTS-0090381Yuriko Renardy, Virginia Polytechnic Institute & State UniversityThe PI proposes to use an advanced numerical code developed by the PI and her group to perform simulations of rheologically-complex two-fluid systems. The code is based on the volume-of-fluid method for interface tracking with additional elements for solving the Navier-Stokes equations and for modeling the interfacial tension. The code will be applied to investigate drop evolution in pipe flow, the evolution of bicomponent flows through channels, the flow of polymer dispersions, and the breakup of droplets. Collaboration with a number of experimental researchers both in this country and abroad is planned.

摘要cts -0090381 yuriko Renardy，弗吉尼亚理工学院和州立大学PI提议使用PI和她的团队开发的高级数字代码来模拟流变学复杂的双流体系统。该代码基于流体体积法进行界面跟踪，并添加了用于求解Navier-Stokes方程和界面张力建模的附加元素。该代码将用于研究管道流动中的液滴演变，双组分流动通过通道的演变，聚合物分散体的流动以及液滴的破裂。计划与国内外的一些实验研究人员合作。
