Non-Equilibrium and Non-Linear Fluids and Related Systems

这个项目的重点是由于流体的非线性和非平衡方面遇到的一些问题。从化学和药物制造到喷墨印刷，流体的操纵在许多技术中都是必不可少的。该项目的一个目标是使用计算机模拟来探索干扰系统的开始，例如使用来自干扰相位图概念的想法。第二个目标是研究在拓扑奇点自发发展的流动液体中发生的转变。实验将研究液滴破裂和选择性退出喷口。这些研究对于基本理解如何处理发生在许多其他科学领域的类似奇点非常重要。一个被提议的目标是开发一种医疗技术，使用选择性提取来覆盖生物材料。由于这类研究大多涉及宏观现象，因此它为本科生，甚至高中生进入实验室提供了一个特别好的起点。博士后研究助理、研究生和本科生将通过参与这些项目进行培训。从化学和药物制造到喷墨印刷，流体的操纵在许多技术中都是必不可少的。这个项目的重点是由于这种无处不在的物质状态的非线性和非平衡方面所遇到的一些问题。该项目的一个目标是使用计算机模拟来探索干扰系统，如使用来自干扰相位图概念的想法的眼镜。第二个目标是研究流动液体中发生的转变。实验将研究液滴破裂和选择性退出喷口。这些研究对于如何处理发生在许多科学领域的奇点的基本理解是重要的。一个提议的目标是用一种医疗技术来覆盖生物材料。培训研究人员在这一广泛领域工作显然对这一领域的未来发展很重要，然而，积极开展这类研究的大学相对较少。由于这类研究大多涉及宏观现象，因此它为本科生，甚至高中生进入实验室提供了一个特别好的起点。博士后研究助理、研究生和本科生将通过参与这些项目进行培训。

This project focuses on some of the problems encountered due to the non-linear and non-equilibrium aspects of fluids. The manipulation of fluids is essential in many technologies from chemical and drug manufacturing to ink-jet printing. One goal of this project is to use computer simulations to explore the onset of jamming in systems such as glasses using ideas that came out of the concept of a jamming phase diagram. A second goal is to investigate transitions occurring in flowing liquids where topological singularities spontaneously develop. Experiments will study drop breakup and selective withdrawal spouts. These studies are important for the basic understanding of how to handle similar singularities that occur in many other areas of science. One proposed objective is for a medical technology that uses selective withdrawal to coat biological material. Because much of this research deals with macroscopic phenomena, it provides a particularly good starting place for bringing undergraduate and, indeed, high-school students into the laboratory. Postdoctoral research associates, graduate, and undergraduate students will be trained by working on these projects.

These studies are important for the basic understanding of how to handle singularities that occur in many areas of science. One proposed objective is for a medical technology to coat biological material. Training researchers to work in this broad area is clearly important for the future growth of this field, however there are relatively few universities where this type of research is actively pursued. Because much of this research deals with macroscopic phenomena, it provides a particularly good starting place for bringing undergraduate and, indeed, high-school students into the laboratory. Postdoctoral research associates, graduate, and undergraduate students will be trained by working on these projects.
