Collaborative Research: Entangled Polymers in Time-Dependent Complex Flows: Experiment & Computation

abstractcts - 0095220 w。这是西北大学和华盛顿大学提交的两份相同提案中的一份。本文提出了一种结合实验和计算的方法来研究粘弹性流体在经过轴对称滞止点的周期性强迫所产生的随时间非均匀流动中的纠缠聚合物。这是西北大学的Wesley Burghardt和华盛顿大学的Bamin Khomami的合作成果，实验部分在西北大学进行，计算部分在华盛顿大学进行。在美国国家科学基金会的支持下，这两位研究者在粘弹性流体的稳定轴对称停滞流动的早期研究中合作成功。他们建议将他们的工作扩展到时间相关的流动，以便在更复杂的流动情况下测试最佳的分子流变模型。

AbstractCTS-0095220W. Burghardt, Northwestern UniversityThis is one of two identical proposals submitted by Northwestern University and Washington University. A combined experimental and computational study is proposed to examine the entangled polymers in a time-dependent inhomogeneous flow generated by periodic forcing of a viscoelastic fluid past an axisymmetric stagnation point. This is a collaborative effort between Wesley Burghardt of Northwestern University and Bamin Khomami of Washington University with the experimental part carried out in the former institution while the computational part in the latter institution. These two investigators have collaborated successfully in an earlier study, with NSF support, of steady axisymmetric stagnation flow of viscoelastic fluids. They are proposing to extend their work to time-dependent flows in order to test the best molecular rheological models in more complex flow situations.
