Travel Support for Conference on Dynamics and Stability of Interfaces

该奖项将支持学生和博士后科学家和工程师参加将于2018年4月2日至5日在盖恩斯维尔的佛罗里达大学举行的IUTAM流体界面动力学和稳定性研讨会。该研讨会将集中在流体和流体/固体之间的界面的模拟和建模。两相流是增材制造、涂层、多孔介质中的流动、飞机除冰以及许多其他自然和工程流动等过程的关键。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。著名专家的专题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，本次会议是及时的。虽然在界面动力学的数值模拟方面取得了重大进展，并且可以从第一原理获得精确的解，但这种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，因此获得与网格无关的结果仍然具有挑战性。可用可靠的降阶模型来表示次网格尺度的物理学将降低计算成本。因此，将计算和建模专家聚集在一起是及时的。鼓励年轻研究人员的参与将有助于满足国家对培养界面流体力学未来工作队伍的需求，并将为年轻研究人员提供一个独特的机会，与该领域的领先研究人员和工业实践者互动。该奖项反映了NSF的法定使命，并被认为值得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来支持。

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.
