ITR: Liquid Atomization: Simulation, Discovery, and Control

这项提议的主要目标是在一个现实的雾化器中实现涉及湍流的液体雾化的第一原理模拟，这比目前的计算能力至少要复杂一个数量级。实现这一目标将促进对液体雾化所需的基本理解。它还将开发一种基于理论的方法，用于设计、控制和优化雾化器，用于汽车、飞机和火箭发动机的超高效、清洁和稳定燃烧，用于制造结构完美材料的喷雾成型，用于液体射流，直到到达高海拔才会雾化，用于灭火以及其他应用。拟议活动的更广泛影响拟议的研究将极大地增强大学的基础设施，通过并行网络RAM和将要开发的科学软件来执行液体雾化的高性能科学计算。在教育和推广方面，这项研究的结果将通过年度CFD短期课程和密歇根州立大学（MSU）举办的研讨会进行传播。密歇根州立大学每年夏天还将为本科生提供暑期实习计划，学生将与该提案的pi一起开展研究。在这个实习项目中，将积极招募来自弱势群体的学生。最后，将开设液体雾化的本科和研究生课程，以教育学生在这一科学计算领域。

The primary objective of this proposal is to enable first-principle simulations of liquid atomization involving turbulence in a realistic atomizer, which is at least an order of magnitude more complicated than is possible today with current computing capabilities. Achieving this objective will facilitate the fundamental understanding needed of liquid atomization. It will also enable the develop of a theory-based method for design, control, and optimization of atomizers for ultra efficient, clean, and stable combustion in automotive, aircraft, and rocket engines, for spray forming that creates structurally perfect materials, for liquid jets that will not atomize until reaching high elevations for fighting fires as well as other applications.Broader Impacts of the Proposed ActivityThe proposed research will greatly enhance the university's infrastructure for performing high-performance scientific computing of liquid atomization through parallel network RAM and the scientific software to be developed.In terms of education and outreach, the results of this research will be disseminated via annual CFD short course and a workshop to be held at Michigan State University (MSU). There will also be a summer internship program for undergraduate students each summer at MSU, where students will work with the PIs of this proposal in carrying out the research. For this internship program, students from under represented groups will be aggressively recruited.Finally, undergraduate and graduate courses will be developed in liquid atomization in order to educate students in this area of scientific computing.
