ABSTRACTPROPOSAL NO.: CTS-0439666PRINCIPAL INVESTIGATORS: MINAMI YODAINSTITUTION: GEORGIA INSTITUTE OF TECHNOLOGYSGER: NOVEL NEAR WALL THERMOMETRY TECHNIQUES WITH SUBMICRON RESOLUTIONThis is an exploratory research program for the development of a technique for measuring fluid temperature to within 100 nm of the wall of a micro-channel. The goal is develop and demonstrate a technique using Dual-Field Fluorescence Thermometry to measure water temperature with 100 micron resolution and within 100 nm from the wall in a micro-channel flow. The intellectual merit of the proposed activity is to enable the non-intrusive measurement of wall temperature in micro-scale devices such as micro-channels with high spatial resolution. Although the technique in principle measures temperature in the fluid, the proximity of the measuring volume (100 nm from wall) is such that the wall temperature can be accurately implied from the near wall fluid temperature. There are currently no proven ways to accurately measure the wall temperature in small-scale internal flows. If successful, the proposed techniques will increase the diagnostic capabilities for analyzing and developing non-isothermal cooling devices such as micro-channel heat sinks. Availability of this new diagnostic tool will have a broad impact on research and application of micro-scale devices that are non-isothermal. Examples principally include devices for cooling high powered electronic processors. Up to now, thermal measurements in internal micro-channel flows have been non-existent. Future development of efficient highly localized cooling solutions for electronics cooling requires improved understanding of these types of flows and the proposed technique adds an important tool to the available diagnostics. The PI is developing a 12-hour introduction to micro- and nano-fluidics to be taught in a 4th year course in applications of fluid mechanics. Results of this project will be included in the proposed course.

ABSTRACTPROPOSAL没有。项目名称：cst -0439666主要研究人员：MINAMI yod研究机构：GEORGIA INSTITUTE OF technology研究人员：新型亚微米分辨率近壁温度测量技术这是一项探索性研究项目，旨在开发一种测量流体温度到微通道壁100纳米范围内的技术。目标是开发和演示一种使用双场荧光测温技术，以100微米分辨率测量水温，距离微通道流壁在100纳米范围内。所提出的活动的智力优点是能够在微尺度设备（如具有高空间分辨率的微通道）中非侵入式测量壁面温度。虽然该技术原则上测量流体中的温度，但由于测量体积（距离壁100纳米）很接近，因此可以从近壁流体温度中准确地推断出壁温度。目前还没有经过验证的精确测量小尺度内部流动壁面温度的方法。如果成功，所提出的技术将增加分析和开发非等温冷却装置（如微通道散热器）的诊断能力。这种新的诊断工具的可用性将对非等温微尺度器件的研究和应用产生广泛的影响。示例主要包括用于冷却高功率电子处理器的装置。到目前为止，还没有对内部微通道流动进行热测量。未来开发高效的、高度本地化的电子冷却解决方案需要更好地理解这些类型的流动，而所提出的技术为现有的诊断增加了一个重要的工具。PI正在开发一个12小时的流体力学导论，将在流体力学应用的第四年课程中教授。该项目的结果将包含在建议课程中。
