This award will support participation of students and postdoctoral scientists and engineers at the IUTAM Symposium on Dynamics and Stability of Fluid Interfaces, which will be held April 2-5, 2018 at the University of Florida, Gainesville. The symposium will focus on the simulation and modeling of interfaces between fluids and fluids/solids. Two phase flows are key to processes including additive manufacturing, coating, flow in porous media, aircraft de-icing, and many other natural and engineered flows. The symposium will bring together computational and modeling experts to address major issues in fluid interfaces and contact lines. Featured lectures by leading experts and round-table discussions will provide a range of learning and networking opportunities for early career scientists and students. The conference is timely in terms of the technical impact and translation to applications. While major advances have been made in the numerical simulation of interfacial dynamics and accurate solutions from first principles can be obtained, the cost of such simulations severely restricts their usefulness. In addition, because topology changes and contact line dynamics take place below the grid resolution, obtaining grid-independent results remains challenging. The availability of reliable reduced-order models to represent sub-grid scale physics would reduce computational costs. Thus, it is timely to bring computational and modeling experts together. Encouraging the participation of young investigators will help fill a national need to train a future work force in interfacial fluid mechanics and will provide a unique opportunity for young investigators to interact with leading researchers and industrial practitioners in this area.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项将支持学生和博士后科学家和工程师参加 IUTAM 流体界面动力学和稳定性研讨会，该研讨会将于 2018 年 4 月 2 日至 5 日在佛罗里达大学盖恩斯维尔分校举行。研讨会将重点讨论流体和流体/固体之间界面的模拟和建模。两相流是增材制造、涂层、多孔介质流动、飞机除冰以及许多其他自然和工程流等工艺的关键。该研讨会将汇集计算和建模专家，以解决流体界面和接触线的主要问题。顶尖专家的特色讲座和圆桌讨论将为早期职业科学家和学生提供一系列学习和交流机会。就技术影响和应用转化而言，这次会议是及时的。虽然界面动力学的数值模拟已经取得了重大进展，并且可以根据第一原理获得准确的解决方案，但此类模拟的成本严重限制了它们的实用性。此外，由于拓扑变化和接触线动态发生在网格分辨率以下，因此获得独立于网格的结果仍然具有挑战性。可用可靠的降阶模型来表示子网格尺度的物理现象将降低计算成本。因此，现在是将计算和建模专家聚集在一起的时候了。鼓励年轻研究人员的参与将有助于满足国家对培训界面流体力学未来劳动力的需求，并将为年轻研究人员提供与该领域领先研究人员和工业从业者互动的独特机会。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
