Non-Equilibrium and Non-Linear Fluids and Related Systems

这个项目关注的是由于流体的非线性和非平衡性而遇到的一些问题。在从化学和药物制造到喷墨打印的许多技术中，流体的操纵都是必不可少的。这个项目的一个目标是使用计算机模拟来探索眼镜等系统中干扰的开始，使用干扰相图概念得出的想法。第二个目标是研究流动液体中发生的相变，在那里拓扑奇点自发发展。实验将研究掉落的分手和选择性的退出喷嘴。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很重要。一个被提议的目标是一种使用选择性退出来覆盖生物材料的医疗技术。因为这项研究大多涉及宏观现象，所以它为把本科生和高中生带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。在从化学和药物制造到喷墨打印的许多技术中，流体的操纵都是必不可少的。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而遇到的一些问题。这个项目的一个目标是使用计算机模拟来探索被干扰的系统，如眼镜，使用来自干扰相图概念的想法。第二个目标是研究流动液体中发生的转变。实验将研究掉落的分手和选择性的退出喷嘴。这些研究对于基本理解如何处理发生在许多科学领域的奇点很重要。一个拟议的目标是让医学技术为生物材料涂上一层。培训研究人员从事这一广泛领域的工作显然对这一领域的未来发展非常重要，然而，积极从事这类研究的大学相对较少。因为这项研究大多涉及宏观现象，所以它为把本科生和高中生带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.
