CAREER: Polymer Molecules in Complex Flows

摘要CTS-0134389 M。Pasquali，Rice University建议通过实验和模拟来研究聚合物在复杂流动中的行为。 该实验由荧光标记的DNA分子以4比1的收缩流动组成，其运动通过视频显微镜观察。 流动的模拟将使用布朗动力学模型和粗粒连续模型进行。 后一种方法将有助于加工设备的设计研究。 教育计划包括引入流变学和高级计算方法的新课程，并将本科生纳入研究。 在推广方面，PI计划每年与一名高中教师合作，帮助将研究经验传授给高中学生。

ABSTRACTCTS-0134389M. Pasquali, Rice UniversityIt is proposed to study experimentally and by simulation the behavior of polymers in complex flow. The experiment consists of fluorescently labeled DNA molecules flowing in a 4 to 1 contraction with its motion observed by video-microscopy. Simulations of the flow will be carried out using both Brownian dynamics model and by the course-grained continuum model. The latter method will lend itself to for design studies of processing equipment. The education plan involves introducing new courses in rheology and advanced computational methods and to include undergraduate students in the research. In terms of outreach, The PI plans to work with one high school teacher per year to help transfer the research experience to the high school students.
