Fluid dynamics and heat transfer of multiphase processes in energy systems will be investigated in this research program. This will include multiphase thermodynamics of wind turbines operating in ice prone regions as well as heterogeneous phase change for salt water freezing, enhanced phase change materials, and multiphase chemical reactions. The primary goal is to improve the performance and efficiency of energy systems, however, other application areas will include chemical processing, oil and gas, and slurry transport. This research program will develop new and improved models, correlations and experimental data for heterogeneous phase change and multiphase flow, including new models to predict ice accretion on wind turbines and marine vessels. These models will lead to more efficient and safer designs by mitigating ice accumulation, as well as increased efficiency of de-icing and anti-icing systems. Predictive models for heterogeneous phase change related to marine icing will be extended to other applications, such as phase change materials with nanoparticles for better designs for thermal energy storage, as well as intra-particle diffusion during chemical reactions for better chemical reactor designs. This research program will improve the viability and sustainability of energy systems in northern regions with harsh weather conditions. This program will contribute to coatings and smart surfaces which will transform ice mitigation and anti-icing systems. Better heat and mass transfer models will allow for more efficient thermal energy storage. Also, it will enable more renewable energy penetration by helping to alleviate problems associated with intermittent power output of wind turbines. Promising potential exists to significantly expand the installed capacity of wind turbines in cold regions of Canada. However, icing causes significant challenges to optimal power output, safety and longevity of turbines operating in these cold regions. By improving the predictive models for ice accretion, the installed capacity of wind turbines can be significantly enhanced in Canada's remote northern regions. Multiphase flows and heterogeneous phase change have important applications to a wide variety of scientific and engineering systems. Icing poses significant challenges to various industrial sectors, such as energy, offshore oil and gas, Arctic development, and northern communities. These are important to Canada's energy economy. This research program will also provide useful benefits to Canada's Arctic sovereignty and shipping, as well as the sustainability of remote northern communities.

本研究计划将研究能源系统中多相过程的流体动力学和传热。这将包括多相热力学的风力涡轮机运行在易结冰的地区，以及非均质相变盐水冻结，增强相变材料，和多相化学反应。其主要目标是提高能源系统的性能和效率，但其他应用领域将包括化学加工、石油和天然气以及泥浆运输。 该研究计划将开发新的和改进的模型，非均相相变和多相流的相关性和实验数据，包括预测风力涡轮机和船舶积冰的新模型。这些模型将通过减少冰积累以及提高除冰和防冰系统的效率来实现更有效和更安全的设计。与海洋结冰有关的非均相变化的预测模型将扩展到其他应用，例如具有纳米颗粒的相变材料，用于更好的热能储存设计，以及化学反应期间的颗粒内扩散，用于更好的化学反应器设计。 这项研究计划将提高北方地区恶劣气候条件下能源系统的可行性和可持续性。该计划将有助于涂层和智能表面，这将改变冰缓解和防冰系统。 更好的传热和传质模型将允许更有效的热能储存。此外，它将通过帮助缓解与风力涡轮机间歇性功率输出相关的问题，实现更多的可再生能源渗透。加拿大寒冷地区风力涡轮机的装机容量有很大的潜力。然而，结冰对在这些寒冷地区运行的涡轮机的最佳功率输出、安全性和寿命造成重大挑战。通过改进积冰预测模型，可以显著提高加拿大偏远北方地区风力涡轮机的装机容量。 多相流和非均相相变在科学和工程系统中有着广泛的应用。结冰对能源、近海石油和天然气、北极开发和北方社区等各个工业部门构成重大挑战。这对加拿大的能源经济至关重要。这项研究计划还将为加拿大的北极主权和航运以及偏远北方社区的可持续性提供有益的好处。
