0138182Ilegbusi Description: This award is for support of a cooperative project between Dr. Olusegun Ilegbusi, Department of Mechanical, Industrial and Manufacturing Engineering, Northeastern University, Boston, Massachusetts and Dr. Mahmut Mat, Department of Mechanical Engineering, Nigde University, Nigde, Turkey. This project is a combined theoretical and experimental study to understand hydrogen development and the hydrodynamics of bubbles in an alkaline electrolyzer. Other parameters to be investigated include current density, applied potential, electrolyte and electrode materials, spacing between the anode, cathode and membrane, and temperature and ambient pressure. A two-phase mathematical model will be developed for the electrolytic process. The model will consider heat and mass transfer, concentrations and ion transport, electricity field, and chemical reaction occurring at the anode and the cathode. Experiments will be designed and performed to validate and improve the mathematical model. The fluid velocity, gas fraction, and bubble growth rate will be measured using Laser Doppler Velocimeter (LDV) at Northeastern University. The ultimate goal of this research is to investigate and develop methods to increase the efficiency of electrolytic production of hydrogen by means of hydrodynamic enhancements. Scope: Hydrogen is one of the promising alternative sources of energy. There is limited systematic investigation on how to quantify and efficiently exploit this energy. The two collaborators plan to combine their expertise in experimental work and mathematical modeling to study this interesting scientific problem. The US PI has considerable experience and has access to extensive facilities at Northeastern University. The Turkish scientist has strong experience in mathematical modeling of two phase heat transfer. This research should improve our understanding of the processes involved in electrolysis to produce hydrogen using water and photovoltaic solar energy. The research will help in establishing the technical framework for cost-effective production and usage of hydrogen energy in Turkey and potentially for other developing countries.

0138182 Ilegbusi描述：该奖项是为了支持马萨诸塞州东北大学机械、工业和制造工程系的Olusegun Ilegbusi博士和土耳其Nigde大学机械工程系的Mahmut Mat博士之间的合作项目。 本计画是一项结合理论与实验的研究，以了解氢的发展与气泡在碱性电解槽中的流体动力学。其他要研究的参数包括电流密度，施加的电势，电解质和电极材料，阳极，阴极和膜之间的间距，以及温度和环境压力。 将为电解过程开发一个两相数学模型。该模型将考虑热量和质量传递，浓度和离子传输，电场，以及在阳极和阴极发生的化学反应。 实验将被设计和执行，以验证和改进的数学模型。流体速度、气体分数和气泡生长速率将使用东北大学的激光多普勒测速仪（LDV）进行测量。 本研究的最终目标是研究和开发通过流体动力学增强来提高电解制氢效率的方法。范围：氢是一种有前途的替代能源。关于如何量化和有效利用这种能源的系统研究有限。 这两位合作者计划将他们在实验工作和数学建模方面的专业知识联合收割机结合起来，研究这个有趣的科学问题。美国PI拥有丰富的经验，并可以使用东北大学的广泛设施。 这位土耳其科学家在两相传热的数学建模方面具有丰富的经验。 这项研究应该提高我们对电解过程的理解，利用水和光伏太阳能生产氢气。该研究将有助于建立技术框架，以在土耳其和其他发展中国家经济高效地生产和使用氢能。
