Characterization and Optimization of Heat Transfer from GRIP Metal Enhanced Surfaces

Nucap工业公司开发了一种以小金属钩(GRIP金属)的形式增强金属表面的新方法。他们已经认识到这种表面结构具有强化换热的潜力；然而，他们并不完全了解GRIP金属设计因素如何影响对流换热性能。这项建议直接满足了Nucap开发知识、模型和设计工具的需求，使他们能够通过开发全面的模型来量化各种流量的传热和各种GRIP金属设计的流体，从而为各种换热应用设计和优化GRIP金属表面。这将通过一系列实验传热学测量以及数值模型和半经验关联式的开发来实现，这些将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其制造工艺为广泛的工业应用开发新的高性能热交换器。此次推出的新型高效热交换器产品线将使Nucap能够在低成本余热回收或高效空间供暖的创新领域定位。该项目可以通过为Nucap位于多伦多的制造工厂创造更多就业机会，为当地经济做出贡献。它还将促进一种新的热交换技术的开发，这将为加拿大工业带来系统效率、更少的浪费和更大的节省。

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.
