This award supports Dr. Gretar Tryggvason and two graduate students from the University of Michigan-Ann Arbor in a collaboration with Martin Sommerfeld of the Department of Mechanical Process and Environmental Protection Engineering at the Martin Luther University in Halle-Wittenberg. The collaboration brings together the complementary capabilities of the German and U.S. groups to study fundamental and applied aspects of multiphase flow. The investigation will involve computational and experimental studies of bubbly flow and will lead to improved engineering models for the average properties of flows in bubble columns. The collaboration will have a direct impact on the modeling of multiphase flows in engineering. Direct numerical simulations are an emerging research tool that is providing both fundamental insight into bubbly flows and direct quantitative data to be used for engineering models in industrial systems.

该奖项支持Gretar Tryggveson博士和密歇根大学安娜堡分校的两名研究生与哈勒-威滕贝格马丁·路德大学机械过程和环境保护工程系的Martin Sommerfeld合作。该合作将德国和美国两个小组的互补能力结合在一起，研究多相流的基本和应用方面。这项研究将涉及泡状流的计算和实验研究，并将改进鼓泡塔内流动平均特性的工程模型。这种合作将对工程中多相流的建模产生直接影响。直接数值模拟是一种新兴的研究工具，它既提供了对泡状流的基本见解，也提供了用于工业系统工程模型的直接定量数据。
