#1435269Zikanov, OlegUniversity of Michigan - Ann ArborEnergy storage is required to reconcile the Nation's demand for uninterrupted energy supply, when utilizing wind or solar energy that are supplied intermittently. A liquid metal battery is a device that can be a promising solution to this problem. The decisive factor, however, for transitioning this technology to the marketplace is the development of a flow instability that shorts the circuit in the battery. The objective of this proposal is to control this instability by advancing understanding of the physical mechanisms responsible for it. The broader impact of this proposal, therefore, is quite important. The proposal also offers a strong education plan, including an international component. The proposed work will contribute to establishing a competitive research environment at the University of Michigan - Dearborn, an institution focused on serving the metropolitan Detroit community. A graduate and several undergraduate students will be involved in the research and results of the project will be incorporated in teaching.This is a proposal with a very fundamental objective that can eventually have an impact in energy storage and in manufacturing. It is focused on hydrodynamic and hydromagnetic instabilities that develop in a liquid metal battery, and it proposes a theoretical and computational analysis leveraged with experiments that will be carried out with an international collaborator. The project advances understanding of complex instabilities in multi-layer fluid systems with electromagnetic effects. The instability mechanisms, some of which are poorly understood, will be analyzed as fully coupled phenomena in the framework of a realistic and practically important system. Advanced techniques of numerical stability analysis will be developed.

当利用间歇性供应的风能或太阳能时，需要密歇根州立大学的#1435269 Zikanov-Ann ArborEnergy存储来协调国家对不间断能源供应的需求。液态金属电池是一种有望解决这一问题的设备。然而，将这项技术转移到市场上的决定性因素是流动不稳定性的发展，这种不稳定会使电池中的电路短路。这项建议的目的是通过促进对造成这种不稳定的物理机制的了解来控制这种不稳定。因此，这一提议的更广泛影响相当重要。该提案还提供了一个强有力的教育计划，包括一个国际组成部分。这项拟议的工作将有助于在密歇根大学迪尔伯恩分校建立一个具有竞争力的研究环境，该机构专注于为底特律大都市社区服务。一名研究生和几名本科生将参与该项目的研究，该项目的成果将被纳入教学。这是一个具有非常根本的目标的提案，最终可能对能源储存和制造业产生影响。它侧重于液态金属电池中形成的流体动力和流体磁不稳定性，并提出了理论和计算分析，并将与国际合作者一起进行实验。该项目促进了对具有电磁效应的多层流体系统中复杂不稳定性的理解。不稳定的机制，其中一些是鲜为人知的，将在一个现实和重要的系统的框架内被分析为完全耦合的现象。将发展先进的数值稳定性分析技术。
