NER: Modeling, Manipulation and Measurement of Enhanced Thermal Transport in Nanostructured Materials

伊利诺伊理工学院我们建议发展纳米结构流体中的传热模型。理论上将对悬浮球形颗粒和单壁碳纳米管进行多尺度计算。提出了分子动力学和布朗动力学相结合的研究方法。为了测试这些模型，将使用一种名为强迫瑞利光散射的新光学技术进行测量。与迄今用于研究类似系统的传统方法相比，该技术具有探测长度和时间尺度小得多的能力。该提案将提供对纳米尺度上的热传输机制的洞察。提出了新颖的分子动力学和布朗动力学模拟方法。此外，新的光学实验技术将提供关于单壁纳米管和纳米流体的独特数据。将获得洞察力，以帮助对纳米尺度上的热传递进行可靠的建模。该项目的进展还将对环境产生重大影响。也就是说，纳米流体已经被提出作为一种替代冷却剂。通过增加冷却剂的流量，大幅提高冷却能力可以显著降低能源成本。少数民族研究生和本科生将接触到一个多学科、理论和实验相结合的项目。

ABSTRACT - 0508498Illinois Institute of TechnologyWe propose here to develop the modelling of heat transfer in nano-structured fluids. Theoretical multiscale computation will be performed for suspended spherical particles, and single-wall carbon nanotubes (SWNT). CombinedMolecular Dynamics and Brownian dynamics studies are proposed. To test the models, measurements will be made using a novel optical technique called Forced Rayleigh Light Scattering. The technique has the ability to probe length and time scales much smaller than the traditional methods used heretofore to study similar systems.IntellectualMerit. The proposal will provide insight into the mechanisms of heat transport on nanometer length scales. Novel molecular dynamics and Brownian dynamics simulations are proposed. Also, novel optical experimental techniques will provide unique data on single-walled nanotubes and nano-fluids.Broader Impact. Insight will be gained to aid in reliable modeling for heat transfer on nanometer length scales. Progress in this project would also provide significant environmental impact. Namely, nanofluids have been proposed as an alternative coolant. Substantial enhancement in cooling can reduce energy costs dramatically over increased flow rate of coolant. Minority graduate students, and undergraduates will be exposed to a multidisciplinary, combined theoretical and experimental project.
