AbstractCTS-0095098B. Khomami, Washington 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.

摘要CTS-0095098B。霍米，华盛顿大学这是西北大学和华盛顿大学提交的两份相同提案之一。 提出了一项实验和计算相结合的研究，以检查粘弹性流体通过轴对称驻点的周期性强迫所产生的时间依赖性非均匀流中的缠结聚合物。 这是西北大学的 Wesley Burghardt 和华盛顿大学的 Bamin Khomami 的合作成果，实验部分在前一个机构进行，计算部分在后一个机构进行。 在美国国家科学基金会的支持下，这两位研究人员在一项早期研究中成功合作，研究粘弹性流体的稳定轴对称停滞流。 他们提议将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。
