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

摘要CTS-0095220 W。Burghardt，西北大学这是西北大学和华盛顿大学提交的两个相同的提案之一。 结合实验和计算研究，提出了检查纠缠的聚合物在一个时间依赖性的非均匀流产生的粘弹性流体的周期性强迫过去的轴对称驻点。 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。 这两个研究人员在早期的研究中成功地合作，与美国国家科学基金会的支持，稳定的轴对称滞止流的粘弹性流体。 他们建议将他们的工作扩展到与时间相关的流动，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.
