项目摘要

The primary focus of the proposed research program is the improved fundamental understanding of single phase convective heat transfer. Knowledge of complex convective heat transfer processes is essential for the skillful design of a wide range of technologies that involve the exchange of heat by a fluid. The engineering applications span all sectors of the economy. In the past Discovery Grant period, the applicant developed a new analytical and numerical approach (called dQdT) that more effectively characterizes convective heat transfer in situations where heat is exchanged between multiple surfaces with multiple driving temperature differences. One goal of the proposed research is to extend this new approach as an experimental method for characterizing multi-temperature convection. This will add a new research technique for investigations, and will enable the validation of numerical predictions by dQdT. Also, the numerical implementation of dQdT will be applied to improve our understanding of the underlying physics of the highly complex flows that are encountered in buildings. The motivation is to refine the accuracy of heat transfer predictions in building energy analysis. Improvements in the capability to predict the thermal performance of buildings will lead to more comfortable and energy efficient designs. Another arm of the proposed research examines the convective heat transfer enhancements that can be achieved using dilute nanofluids. Nanofluids combine nanoparticles and base fluids to create working fluids that have the potential for use in a wide range of cooling technologies. At present, the magnitude and mechanisms of the convective heat transfer enhancement remain poorly understood. The proposed research will investigate this effect for transparent water-based nanofluids, using an optical measurement technique called laser interferometry. The ability of optical methods to quantify and visualize the entire fluid temperature field opens up important opportunities for new fundamental insights into the heat transfer enhancements produced by dilute nanofluids. The proposed research will be undertaken as an integrated program involving a balance between state-of-the-art experimental methods and computational fluid dynamics modeling. This research will provide excellent training experiences for doctoral, master's and undergraduate students, and will lead to fundamental advances in the field of convective heat transfer.
拟议的研究计划的主要重点是改善单相对流传热的基本理解。复杂的对流传热过程的知识对于熟练设计涉及流体热交换的各种技术至关重要。工程应用涵盖经济的所有部门。在过去的发现资助期间,申请人开发了一种新的分析和数值方法(称为dQdT),该方法更有效地表征了在具有多个驱动温差的多个表面之间进行热交换的情况下的对流热传递。所提出的研究的一个目标是将这种新方法扩展为表征多温度对流的实验方法。这将为调查增加一种新的研究技术,并将使dQdT的数值预测的验证。此外,dQdT的数值实现将被应用于提高我们对建筑物中遇到的高度复杂的流动的基本物理的理解。其动机是改进建筑物能量分析中传热预测的准确性。预测建筑物热性能的能力的提高将导致更舒适和节能的设计。拟议研究的另一个分支研究了使用稀释纳米流体可以实现的对流传热增强。纳米流体联合收割机结合纳米颗粒和基础流体,以创造具有在广泛的冷却技术中使用的潜力的工作流体。目前,对流换热强化的大小和机制仍然知之甚少。拟议的研究将使用一种称为激光干涉测量法的光学测量技术来研究透明水基纳米流体的这种效应。光学方法的能力,量化和可视化的整个流体温度场开辟了重要的机会,新的基本见解的传热增强所产生的稀释纳米流体。 拟议的研究将作为一个综合计划进行,涉及最先进的实验方法和计算流体动力学建模之间的平衡。这项研究将为博士,硕士和本科生提供优秀的培训经验,并将导致对流传热领域的根本性进展。
