Novel Numerical Techniques for Complex Fluids Modeling

该奖项由2009年美国复苏和再投资法案(公法111-5)资助。非牛顿流体或复杂流体在我们的日常生活中大量存在。这类流体的例子包括熔融的塑料、带有聚合物添加剂的发动机油、油漆、蛋清和血液。突破性技术可以来自实验或通过利用新的建模方法，这些方法有可能提供对可能的过程的快速筛选。更有可能的是，模拟将在提供对这项突破性技术的基本理解方面发挥更大的作用。通过模型捕捉到这一基本理解提供了实际操作设备和基本机械信息之间的连接，并允许对过程可行性进行更现实的评估。模型提供了扩展运行参数空间的基础，并对建造全尺寸的决策和最终设计的性质具有重要影响。对非牛顿力学等重要领域进行精确的设计、高效的实施和使用数值方法进行计算机模拟，将会有重要的应用。一旦建立了计算模型包，就将向公众开放。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Non-Newtonian fluids or complex fluids are abundant in our daily lives. Examples of such fluids include molten plastics, engine oils with polymeric additives, paints, egg white and blood. Breakthrough technology can come from experiments or through utilization of new modeling methods that have the potential to provide rapid screening of possible processes. More likely is that simulation will play a greater role in providing a fundamental understanding of the breakthrough technology. Capturing this fundamental understanding with models provides the connectivity between an actual practical operating device and fundamental mechanistic information and allows for a more realistic assessment of process viability. Models provide the basis of extending the operating parameter space and have a significant impact on the decision to build the full scale and on the nature of the ultimate design. The accurate design, efficient implementation, and the use of numerical methods for the computer simulation of such important fields as non-Newtonian mechanics will result in significant applications. The computational modeling package, once established, will be made for the public use.
