Characterization and Optimization of Heat Transfer from GRIP Metal Enhanced Surfaces

NUCAP工业开发了一种新的方法，以小金属挂钩的形式增强金属表面（GRIP metal）。他们已经认识到这种表面结构具有增强传热的潜力；然而，他们并不完全了解GRIP金属设计因素如何影响对流传热性能。该提案直接解决了NUCAP需要开发的知识，模型和设计工具，使他们能够设计和优化GRIP金属表面广泛的热交换应用，通过开发全面的模型来量化热传递范围广泛的流量和流体的GRIP金属设计。这将通过一系列的实验传热测量，结合数值模型和半经验相关性的发展来完成，这些将共同作为设计工具，并帮助优化GRIP金属制造参数，以实现给定的热交换设计目标。结果将使他们能够利用他们的制造工艺，为广泛的工业应用开发新的高性能热交换器。这一新颖有效的热交换器产品线的推出将使NUCAP能够在低成本废热回收或高效空间加热的创新领域中定位自己。该项目可以为NUCAP在多伦多的制造工厂创造更多就业机会，从而为当地经济做出贡献。它还将促进新型热交换技术的发展，从而提高系统效率，减少浪费，并为加拿大工业节省更多资金。

NUCAP Industries has developed a novel method of enhancing the surface of metals in the form of small metal hooks (GRIP Metal). They have recognized the potential this surface structure holds for the enhancement of heat transfer; however, they do not have a complete understanding of how GRIP Metal design factors affect convective heat transfer performance. This proposal directly addresses NUCAP's need to develop the knowledge, models and design tools to allow them to design and optimize GRIP Metal surfaces for a wide range of heat exchange applications by developing comprehensive models to quantify heat transfer for a wide range of flowrates and fluids for a range of GRIP Metal designs. This will be accomplished through a series of experimental heat transfer measurements in conjunction with the development of numerical models and semi-empirical correlations which together will serve as design tools and help optimize GRIP Metal fabrication parameters for a given heat exchange design goal.The results will allow them to leverage their fabrication process to enable the development of new high-performance heat exchangers for a wide range of industrial applications. This launch of a novel and effective heat exchanger product line will allow NUCAP to position themselves in the innovative area of low-cost waste heat recovery or efficient space heating. This project could contribute to the local economy by creating more jobs at NUCAP's manufacturing facility in Toronto. It will also facilitate the development of a novel heat exchange technology which will result in system efficiencies, less waste, and greater savings for Canadian industries.
