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.

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技术大学热力学研究所的F. Mayinger教授合作。 他们的研究的目的是量化和更好地了解超临界，自我维持的振荡性流中的传热物理，例如在紧凑型热交换器中发现的用于冷却电子系统的热量流。 其联合研究的数值和分析部分将在Amon教授的指导下在CMU开发。 该研究的实验部分将使用实时全息干涉法和高速摄影在慕尼黑技术大学在慕尼黑技术大学进行。 传热在许多机械和电子系统的可靠性和效率中起重要作用。 在需要紧凑的热交换表面的系统的设计中，优化这种转移的关注越来越多。 这些包括在能源相关的设备，电子冷却，低温和航空航天应用中的许多应用。 拟议的合作研究将开发并验证增强传热的数学模型。
