Description: This award supports a collaborative research project between Dr. Awatef A. Hamed and Dr. Widen Tabakoff, both professors at the Department of Aerospace Engineering and Engineering Mechanics at the University of Cincinnati, with Dr. Reda Mankbadi, Professor of Mechanical Engineering at Cairo University in Egypt. The research deals with the particle dynamics and jet noise of gas-particle flows in supersonic nozzles. The U.S. team will conduct experimental studies and develop models for simulating the particle dynamics and their interactions with the high Reynolds number flow through the convergent-divergent nozzle. The Egyptian scientist will develop the techniques for calculating the noise from the ensuing supersonic particle-flow jet. Scope: This project involves collaboration of a U.S. experimental fluid mechanics team with an Egyptian expert in computational fluid dynamics and acoustics research. The complementarity in this cooperative research is expected to be beneficial to the two sides and should lead to a better research output. Both teams have, independently, done extensive work in the field, with very strong records of publications. This project is to have them combine their skills, competence, and facilities to advance the knowledge in an area of great importance in aerospace engineering, and in environmental engineering in various industries. The beneficiaries in advances in this field include, in part, designers and manufacturers of aircraft engines, ground-based gas turbines and other propulsion and power plant systems. This award is being funded jointly by the Division of International Programs and the Division of Chemical and Transport Systems.

描述：该奖项支持辛辛那提大学航空航天工程与工程机械师系的教授Widen Tabakoff博士和Widen Tabakoff博士之间的合作研究项目，以及埃及的开罗大学。 该研究涉及超音速喷嘴中气体流动的粒子动力学和喷气噪声。 美国团队将进行实验研究，并开发模型，以模拟粒子动力学及其与高雷诺数通过收敛发散喷嘴流动的相互作用。 埃及科学家将开发用于计算随后的超音速粒子射流中噪声的技术。 范围：该项目涉及美国实验流体力学团队与埃及计算流体动力学和声学研究专家的合作。 预计这项合作研究的互补性将对双方有益，并应带来更好的研究成果。 两支球队都独立地在该领域完成了广泛的工作，并具有非常强大的出版物记录。 该项目是让他们结合自己的技能，能力和设施，以在航空航天工程中非常重要的领域以及各个行业的环境工程中提高知识。 该领域进步的受益人部分包括飞机发动机的设计师和制造商，地面燃气轮机以及其他推进和发电厂系统。 该奖项由国际计划和化学和运输系统部共同资助。
