Workshop on Micro and Nano Structures for Phase Change Heat Transfer

CBET-1261824 PI：Peles在过去十年中，微米和纳米工程结构上的沸腾、蒸发和冷凝受到了极大的关注。现在很明显，表面上的这种结构对推进液-汽相变系统有很大的希望，并且是实现超高热通量系统（例如计算机处理单元（CPU）、激光二极管和功率放大器）的热管理的关键。因此，这些领域的研究工作显著增加，在最近的会议上出现了重大成果。然而，仍然需要对复杂的相变过程的全面理解，这是目前缺乏的，以利用这些过程的各种设备和重要的应用。此外，需要制定一个路线图，确定未来一代相变技术的需求。本次研讨会解决了这些缺点，并为工业，政府机构和学术界提供了一个路线图，以加速和优化微纳米技术提供的上级传热方法的开发。为实现这些目标，讲习班侧重于：1）相变过程的最新知识，2）建模，计量，操作能力的进步，3）相变研究的变革机会和未来方向，（4）发展阶段-改变设备和应用程序。赠款通过帮助创建一个论坛来支持这个研讨会，该论坛汇集了来自各个学科的专家，当前和未来的重大热管理挑战。NSF的支持还允许将邀请扩展到年轻的参与者以及真正的先锋参加这个研讨会。该研讨会汇集了来自机械工程，化学工程和材料科学等各个学科的专家，重点是传热界，以确定相变研究的关键挑战，进步和新方向。为期两天的广泛研讨会确定了关键的研究，开发和设计需求，并为未来的努力提供了指导方针。本次研讨会的成果集中于制定一个路线图，该路线图定义了未来一代相变技术的需求，并记录在归档评论文章中。

CBET-1261824PI: Peles Boiling, evaporation, and condensation on micro and nano engineered structures have received significant interest over the last decade. It is now evident that such structures on surfaces hold great promise to advance liquid-vapor phase change systems and are key to enable thermal management of ultra-high heat flux systems, such as computer processing units (CPUs), laser diodes, and power amplifiers. Accordingly, there has been a significant increase in research efforts in these areas with a significant emergence in recent conferences. However, comprehensive understanding of complex phase-change processes is still needed, which is currently lacking, to harness these processes for various devices and important applications. Furthermore, a roadmap that defines the needs for the future generation of phase-change technologies needs to be developed. This workshop address these shortcomings and provide a roadmap to industry, government agencies, and the academic communities to accelerate and optimize the development of superior heat transfer methods offered by micro and nano technologies. To achieve these goals, the workshop focuses on: 1) State-of-the-art knowledge of phase change processes, 2) Advancements in modeling, metrology, manipulation capability, 3) Transformative opportunities and future directions for phase-change research, and 4) Development of phase-change devices and applications.The grant supports this workshop by helping create a forum that brings together experts from various disciplines that will solve significant current and future thermal management challenges. The NSF support also allows extending the invitation to young participants as well as true pioneers to this workshop. The workshop brings together experts from various disciplines including mechanical engineering, chemical engineering and material science, with an emphasis on the heat transfer community to identify critical challenges, advancements, and new directions in phase-change research. The two-day extensive workshop identifies key research, development, and design needs, and provides a guideline for such future endeavors. The outcome of this workshop is focused on developing a roadmap that defines the needs for the future generation of phase-change technologies, as well as documented in archival review articles.
