项目摘要
The ability to transfer heat quickly and efficiently across modest distances is essential to many engineering industries e.g. aerospace, electronics and HVAC. An especially effective device for accomplishing this task is the heat pipe, which, in its simplest incarnation, consists of a closed metal tube inside of which is a working fluid that respectively evaporates and condenses where the tube is hot and cold.Working with a Canadian company committed to fabricating novel heat transfer and air handling equipment, we will use new advances in surface science and micro-fluidics to better understand heat pipe operation with a view towards improving performance through better design. In addition to generating new knowledge and training a variety of students, our major (industrial) deliverable will be a computer program capable of informing design decisions. The program in question will leverage four decades of original research in the field and will also make use of new results generated through our laboratory program. More specifically, we plan to experimentally test the feasibility of using surface chemical treatments to modify the surface energy of the wick, the component internal to the heat pipe that passively "pumps" condensed liquid back to the hot end of the heat pipe. Through such a chemical treatment, we hope to realize favourable regimes of evaporation and condensation and to separately minimize entrainment, the process by which liquid droplets are sheared away from the wick. In a related theoretical effort, we plan to adapt ideas from core annular flow theory so as to improve the dynamical description of the liquid-vapour counterflow.Results from our study will be both communicated in the scientific literature and also adapted for pragmatic application by the industrial partner. In this latter respect, we envision making a key technical contribution by improving the design capabilities and also the profitability of a Canadian company eager for new opportunities.#(cr)#(lf)This section intentionally left blank.
在适当的距离内快速有效地传递热量的能力对许多工程行业至关重要,例如航空航天,电子和HVAC。一个特别有效的装置来完成这项任务是热管,它,在其最简单的化身,由一个封闭的金属管,其中是一个工作流体,分别蒸发和冷凝管是热的和冷的。工作与加拿大公司致力于制造新的传热和空气处理设备,我们将利用表面科学和微流体技术的新进展,更好地了解热管的运作,以期通过更好的设计来提高性能。除了产生新的知识和培训各种各样的学生,我们的主要(工业)交付将是一个计算机程序,能够通知设计决策。该项目将利用该领域40年的原创研究,并将利用我们实验室项目产生的新成果。更具体地说,我们计划通过实验测试使用表面化学处理来改变芯的表面能的可行性,芯是热管内部的组件,其被动地将冷凝液体“泵”回热管的热端。通过这样的化学处理,我们希望实现蒸发和冷凝的有利制度,并分别最大限度地减少夹带,液滴被剪切离开芯的过程。在相关的理论工作中,我们计划采用核心环形流理论的思想,以改善液-汽逆流的动力学描述。我们的研究结果将在科学文献中进行交流,并由工业合作伙伴进行实际应用。在后一个方面,我们设想通过提高设计能力和渴望新机会的加拿大公司的盈利能力来做出关键的技术贡献。(cr)#(lf)本节有意留空。
