Collaborative Research: International Nanofluid Properties Benchmark Exercise (INPBE)

该项目部分支持国际纳米流体特性基准测试（INPBE），最终将于2008年9月至11月在美国大陆举行为期两天的研讨会。本次研讨会和相关的“循环”测试的目的是减少围绕纳米级胶体溶液（通常称为“纳米流体”）热物理性质的巨大不确定性。在NSF内部，资金由热传输过程（TTP）计划和颗粒与多相过程（PMP）计划提供。就知识价值而言，由于缺乏对其热物理性质的基本了解，开发用于热和其他应用的纳米流体的进展受到阻碍。许多不一致的实验报告困扰着文献，使得很难制定明确的模型来描述纳米流体中的热传输。这一合作研讨会提案解决了这些突出的问题，建议世界各地相对较多的感兴趣的实验室测量名义上相同的纳米流体样品的导热性，这些样品是由同一制造商从单个批次中制备的。之后，来自参与实验室的代表将在为期两天的研讨会上会面，讨论他们的成果并规划未来的活动。更广泛的影响包括部分支持一些妇女和少数民族研究人员参与这项工作，并参加为期两天的讲习班。提高对纳米流体的基本理解？传输特性可以使其应用于许多热系统，从而提高效率并降低能耗。由于一些参与的实验室位于美国以外，该项目也将有助于加强国际合作。

CBET-0812902, VenerusThis project partially supports the International Nanofluid Properties Benchmark Exercise (INPBE), culminating in a two-day workshop which will be held in the continental U.S. in the September - November, 2008, time frame. The purpose of this workshop and associated 'round-robin' testing is to reduce the great uncertainties surrounding the thermophysical properties of nanoscale colloidal solutions, popularly termed 'nanofluids.' Within NSF, funding is provided by both the Thermal Transport Processes (TTP) Program and the Particulate & Multiphase Processes (PMP) Program.With respect to the intellectual merit, progress in developing nanofluids for thermal and other applications is hindered by a lack of fundamental understanding of their thermophysical properties. A number of inconsistent experimental reports have plagued the literature, making it difficult to formulate definitive models to describe thermal transport in nanofluids. This collaborative workshop proposal addresses these outstanding issues by proposing that a relatively large number of interested laboratories around the world measure the thermal conductivity of nominally identical nanofluid samples, prepared from a single batch by the same manufacturer. Afterwards, representatives from the participating laboratories will meet in a two-day workshop to discuss their results and to plan future activities. The broader impacts include partial support for a number of women and minority researchers to participate in this exercise, and to attend the two-day workshop. Improved fundamental understanding of nanofluids? transport properties may lead to their application in a number of thermal systems, resulting in improved efficiencies and reduced energy consumption. Since a number of the participating laboratories are located outside the US, this project will also serve to enhance international collaboration.
