#1435269Zikanov，密歇根大学奥列格-安娜堡能源存储需要调和国家的不间断能源供应的需求，当利用间歇性供应的风能或太阳能。液态金属电池是解决这个问题的一种有前途的设备。然而，将这项技术推向市场的决定性因素是流动不稳定性的发展，这种不稳定性会使电池中的电路短路。该提案的目的是通过促进对造成不稳定的物理机制的理解来控制这种不稳定性，因此，该提案的更广泛影响是非常重要的。该提案还提供了一个强有力的教育计划，包括国际组成部分。拟议的工作将有助于在密歇根大学-迪尔伯恩建立一个有竞争力的研究环境，这是一个专注于为底特律大都市社区服务的机构。一名研究生和几名本科生将参与研究，该项目的结果将纳入教学。这是一个具有非常基本目标的提案，最终可能对能源存储和制造业产生影响。它专注于液体金属电池中发展的流体动力学和磁流体不稳定性，并提出了一种理论和计算分析，并将与国际合作者一起进行实验。该项目推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。的不稳定机制，其中一些是知之甚少，将被分析为一个现实的和实际上重要的系统的框架中的完全耦合的现象。将开发数值稳定性分析的先进技术。

#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.
