项目摘要
Heat is omnipresent in today's society from microelectronics to industrial processes to solar radiation. Thermal conversion and management of these heat sources is a growing field of study as new products generate greater heat loads and as society looks to expand its use of solar energy. Indeed, single phase thermal management strategies are being replaced with two-phase heat exchangers for precision temperature control and for other practical reasons such as size and weight reduction. However, there lacks reliable predictive capabilities of the heat transfer rates associated with nucleate boiling due to the coalescence of multiphase thermal fluid mechanisms. Greater insight into the underlying mechanisms is therefore required to assist in the design and optimization of novel thermal management strategies. ***The purpose of the present program is to extend the predictive capabilities of the Capillary equation for inclined nucleate boiling and for gas formations in an electric field, to apply the thermelectric effect to multiphase systems and to convert the heat of solar radiation to electricity. In improving our understanding of the effect of electrostatic forces on bubble evolution, models more accurately predicting the heat transfer control of an electric field may be developed. The impact of this work gravitates towards heat exchanger designs for which nucleation sites are on an incline and for which the heat transfer rate is passively controlled through the electrohydrodynamic interaction between an electric field and a fluid. The motivation for this work is to improve efficiency and the running capacity of industrial processes. In this capacity, the present research program will extend the multiphase thermal management strategies to remote electronic devices that are typically limited to single phase heat diffusion techniques due to industry restrictions. Novel thermoelectric solutions to the problem will be presented providing a trajectory to light weight and reliable heat exchangers for the topical Canadian Information Technology and Communication industry. Furthermore, novel solar radiation heat recovery techniques will be explored in an effort to move towards an efficient thermoelectric conversion technique of the most abundant source of heat, solar thermal energy.**
在当今社会,从微电子到工业过程再到太阳辐射,热量无处不在。这些热源的热转换和管理是一个不断增长的研究领域,因为新产品产生更大的热负荷,并且社会希望扩大其对太阳能的使用。事实上,单相热管理策略正在被两相热交换器所取代,以实现精确的温度控制和其他实际原因,如尺寸和重量的减少。然而,由于多相热流体机制的聚结,与核态沸腾相关的传热速率缺乏可靠的预测能力。因此,需要更深入地了解潜在的机制,以帮助设计和优化新的热管理策略。* 本程序的目的是扩展毛细管方程对倾斜核沸腾和电场中气体形成的预测能力,将热电效应应用于多相系统,并将太阳辐射的热量转换为电能。为了提高我们对静电力对气泡演化的影响的理解,可以开发更准确地预测电场的传热控制的模型。这项工作的影响倾向于热交换器的设计,其中成核位点是在一个倾斜的,并通过电场和流体之间的电流体动力相互作用的热传递速率是被动控制。 这项工作的动机是提高效率和工业过程的运行能力。在这个能力,本研究计划将扩展多相热管理策略,以远程电子设备,通常限于单相热扩散技术,由于行业的限制。将提出新的热电解决方案,为加拿大信息技术和通信行业的主题提供一个重量轻,可靠的热交换器的轨迹。此外,还将探索新的太阳辐射热回收技术,努力实现最丰富的热源-太阳热能-的有效热电转换技术。
