Collaborative Research: International Nanofluid Properties Benchmark Exercise (INPBE)

CBET-0812902，VenerusThis项目部分支持国际纳米流体性能基准测试（INPBE），最终将在2008年9月至11月在美国大陆举行为期两天的研讨会。 这个研讨会和相关的“循环”测试的目的是减少纳米级胶体溶液（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）计划和颗粒多相过程（PMP）计划提供。关于知识价值，由于缺乏对其热物理性质的基本理解，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。 这个合作研讨会的建议解决了这些悬而未决的问题，建议世界各地相对大量的感兴趣的实验室测量名义上相同的纳米流体样品的热导率，从同一制造商的一个单一批次制备。 随后，参与实验室的代表将参加为期两天的研讨会，讨论他们的结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群体研究人员参加这项工作，并参加为期两天的讲习班。 提高对纳米流体的基本理解？传输特性可能导致它们在许多热系统中的应用，从而提高效率并降低能耗。 由于许多参与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.
