NUCAP has developed a manufacturing process which creates high aspect ratio metal features on metal**surfaces and wish to explore the potential of this unique surface geometry for enhanced convective heat**transfer from metal heat exchanger fins. The objectives of this research project are to characterize the**thermo-fluidic performance of these heat exchangers and to develop design tools which can be used to**optimize these features for given customer requirements.**The research team will develop the test facilities and characterize both water-to-air and air-to-air heat**exchangers fabricated using conventional methods and NUCAP's surface enhancements. This work is**innovative in that it represents the first time convective heat transfer from these unique structures will be**quantified and compared to existing heat exchanger technologies. Recently developed pin-fin models will be**reviewed and modified as necessary to the unique geometries here. A 3D surface reconstruction technique will**be employed to support geometric analysis and subsequent numerical models for heat transfer from these**features.**This project will benefit NUCAP by quantifying the heat transfer enhancement offered by their fabrication**technique and to support the development of a new product line and revenue stream for NUCAP. It will further**provide the modelling and design tools to improve their designs and meet the needs of a wide range of potential**customers. A positive outcome of this research project will contribute to creation of more jobs at NUCAP's**manufacturing facility in Toronto. It will further facilitate the development of a novel heat exchange**technology for Canadian industries such as energy storage, HVAC, and solar thermal collectors.

NUCAP已经开发出一种制造工艺，可以在金属表面上创造高纵横比的金属特征，并希望探索这种独特的表面几何形状的潜力，以增强金属热交换器翅片的对流热传递。本研究项目的目标是表征这些热交换器的热流体性能，并开发设计工具，可用于根据特定客户要求优化这些功能。**研究小组将开发测试设备，并对使用传统方法和NUCAP表面增强制造的水-空气和空气-空气热交换器进行表征。这项工作具有创新性，因为它首次将这些独特结构的对流换热量化，并与现有的热交换器技术进行比较。最近开发的针鳍模型将**审查和修改为必要的独特的几何形状在这里。3D表面重建技术将用于支持几何分析和随后的数值模型，以从这些特征传热。**该项目将使NUCAP受益，量化其制造技术提供的传热增强，并支持NUCAP新产品线和收入流的开发。它将进一步**提供建模和设计工具，以改善他们的设计，满足广泛的潜在客户的需求。该研究项目的积极成果将有助于在NUCAP位于多伦多的**制造工厂创造更多就业机会。它将进一步促进一种新型热交换技术的发展，适用于加拿大的能源储存、暖通空调和太阳能集热器等行业。
