U.S.-Germany Cooperative Research on Heat Transfer Enhancement in Self-Sustained Oscillatory Flows

该奖项支持卡内基梅隆大学(CMU)的克里斯蒂娜·阿蒙教授与德国慕尼黑工业大学热力学研究所的F.Mayinger教授在机械工程研究方面进行合作。他们的研究目的是量化和更好地理解超临界、自持续、振荡流动中的传热强化物理，例如用于冷却电子系统的紧凑型热交换器中的那些流动。他们联合研究的数值和分析部分将在CMU的阿蒙教授的指导下进行。这项研究的实验部分将由梅因格教授和其他人在慕尼黑工业大学进行，使用实时全息干涉测量和高速摄影。热传递对许多机械和电子系统的可靠性和效率起着重要的作用。在需要紧凑换热表面的系统设计中，优化换热越来越受到重视。这包括在能源相关设备、电子冷却、低温和航空航天应用中的许多应用。建议的合作研究将开发和验证强化换热的数学模型。

This award supports Professor Cristina Amon of Carnegie Mellon University (CMU) to collaborate in mechanical engineering research with Professor F. Mayinger of the Institute for Thermodynamics of the Technical University of Munich, Germany. The objective of their research is to quantify and gain a better understanding of the physics of heat transfer enhancement in supercritical, self-sustained, oscillatory flows, such as those found in compact heat exchangers for cooling electronic systems. The numerical and analytical part of their joint research will be developed at CMU under the direction of Professor Amon. The experimental part of the research will be conducted at the Technical University of Munich by Professor Mayinger and others, using real-time holographic interferometry and high-speed cinematography. Heat transfer plays an important role in the reliability and efficiency of a great many mechanical and electronic systems. Optimizing such transfer is being given more and more attention in the design of systems needing compact heat exchange surfaces. These include many applications in energy-related devices, electronic cooling, cryogenics and aerospace applications. The proposed cooperative research will develop and validate a mathematical model of heat transfer enhancement.
