CDS&E-ENG: A Novel Approach for Oceanographic Explorations: Multi-Scale Modeling and Simulation using CFD Enabled by AUVs Data

这笔赠款的研究目的是通过计算了解负责海洋运输的基本机制，这些计算是通过移动传感器网络收集的数据实现的。水的运动为地球化学和生物通量提供能量，并在所有海洋深度的大空间尺度上发生。湍流是海洋流动的一种自然特征，对沉积物、污染物和营养物等物质在周围环境中的分散和沉积起着重要作用。尽管进行了广泛的研究，但由于缺乏直接测量，海洋湍流及其对泥沙夹带和迁移等质量传输过程的影响程度仍然知之甚少。在这项研究中，将采用一种多尺度的建模和仿真方法，使用由专门设计的自主水下机器人提供数据支持的计算模型。如果成功，这项研究将大大加强海洋观测，并使以前无法获得的测量成为可能。该项目将结合计算和数据启用科学的最新发展，并将它们与经典工作结合在一起，形成本科生和研究生水平的创新教育计划；这一跨学科项目将强调对潜在的计算和动力系统过程的基本理解。仅加州大学伯克利分校的工程和计算机科学学院就有24%的本科生是少数族裔(非洲裔美国人、西班牙裔美国人和美国印第安人)，14%是女性。这一多样化的学生群体使这一项目能够招募少数族裔学生和女性学生。此外，通过这笔赠款支持的外展活动，该项目将在更广泛的人群中培养对计算和动力系统科学的兴趣，并更广泛地促进跨学科的科学和工程文化，这将对所有学生的职业生涯产生长期影响。

The research objective of this grant is to understand the fundamental mechanisms responsible for marine transport through computations that are enabled by data collected through a mobile sensor network. The movement of water provides the energy for geochemical and biological fluxes and occurs over large spatial scales at all ocean depths. Turbulence is a natural characteristic of ocean flows and plays an important role in how materials such as sediment, pollutants and nutrients are dispersed and deposited in the surrounding environment. In spite of the extensive studies, ocean turbulence and the extent to which it influences mass transport processes, such as sediment entrainment and transport, remain poorly understood because of the lack of direct measurements. In this research, a multi-scale modeling and simulation approach using computational models that are data-enabled by specially designed autonomous underwater vehicles will be pursued. If successful, this research will significantly enhance the ocean observations and will enable previously unobtainable measurements.This project will incorporate recent developments in computational and data-enabled sciences and will combine them with classical work into an innovative educational program at the undergraduate and graduate levels; this interdisciplinary project will emphasize fundamental understanding of the underlying computational and dynamical system processes. UCF's College of Engineering and Computer Science alone has an undergraduate student population of 24 percent minority (African-American, Hispanic, and American Indian) and 14 percent female. This diverse student population enables the recruitment of minority and female students into this project. In addition, through outreach activities supported by this grant, this project will foster an interest in computational and dynamical systems sciences in the broader population and more generally promote an interdisciplinary scientific and engineering culture that will have a long-term impact on all students throughout their careers.
