ITR: Liquid Atomization: Simulation, Discovery, and Control

这项提议的主要目标是实现在现实雾化器中涉及湍流的液体雾化的第一性原理模拟，这至少比目前的计算能力复杂一个数量级。实现这一目标将有助于对液体雾化所需的基本理解。它还将使开发一种基于理论的方法来设计、控制和优化雾化器，用于汽车、飞机和火箭发动机中的超高效、清洁和稳定的燃烧，用于喷射成型，创建结构完美的材料，用于液体喷嘴，直到达到高海拔才会雾化，用于灭火和其他应用。拟议活动的广泛影响拟议的研究将极大地加强大学的基础设施，通过并行网络RAM和即将开发的科学软件进行高性能的液体雾化科学计算。在教育和推广方面，这项研究的结果将通过每年一次的CFD短期课程和在密歇根州立大学(MSU)举行的研讨会来传播。每年夏天，密歇根州立大学还将为本科生提供暑期实习计划，学生们将与这项计划的PI一起开展研究。在这个实习计划中，将积极招募来自代表性不足群体的学生。最后，将开发液体雾化本科和研究生课程，以教育学生在这一科学计算领域的知识。

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.
