Canada's abundant energy supply has led to a significant reliance on energy to sustain our quality of life and to power our key industrial sectors. Given the rising cost and demand for energy worldwide as well as the growing concern over the role that fossil fuels play in both climate change and health risks, there is an urgent need to develop cleaner and sustainable alternatives as part of Canada's energy strategy. Thermal energy conversion and management is a core technology that can be applied to numerous applications, including the capture of waste heat from energy systems, vehicles and commercial or industrial processes. These systems hold enormous potential to augment conventional energy sources in the short term and to revolutionize the way we produce energy in the future. This research is motivated by a critical need for novel devices and systems to capture this "lost" energy. Combining scientific expertise, exploratory research and enabling technologies, the objective of this research program is to develop solutions that are urgently required to overcome the technological barriers that are preventing advanced concepts from being translated into systems that can meet society's needs. This includes the development of expertise in two-phase thermal management systems, new heat exchanger designs and advanced thermal storage solutions by establishing electrohydrodynamics (EHD) as the mechanism of enhancement and intelligent control. The EHD principle involves interaction of an applied electric field with a fluid medium to induce electric body forces on the fluid, and set the fluid in motion. This impact then provides the ability to significantly enhance heat transfer as well as the ability to control it. The long term research goal will be to establish analytical methods and design guidelines to facilitate the wide scale employment of these novel systems in order to maximize the potential of the EHD effect. The resulting knowledge will provide HQP with the methods and tools to integrate existing thermal management and conversion systems with these critically needed novel technologies, turning waste heat into useable energy.

加拿大丰富的能源供应导致了对能源的严重依赖，以维持我们的生活质量和为我们的主要工业部门提供动力。鉴于全世界对能源的成本和需求不断上升，以及对化石燃料在气候变化和健康风险中所起作用的日益关注，迫切需要开发更清洁和可持续的替代品，作为加拿大能源战略的一部分。热能转换和管理是一项核心技术，可应用于许多应用，包括从能源系统、车辆和商业或工业过程中捕获废热。这些系统具有巨大的潜力，可以在短期内增加传统能源，并在未来彻底改变我们生产能源的方式。这项研究的动机是迫切需要新的设备和系统来捕获这种“丢失”的能量。结合科学专业知识，探索性研究和使能技术，该研究计划的目标是开发解决方案，迫切需要克服阻碍先进概念转化为满足社会需求的系统的技术障碍。这包括通过建立电流体动力学（EHD）作为增强和智能控制机制，开发两相热管理系统的专业知识，新的热交换器设计和先进的储热解决方案。EHD原理涉及外加电场与流体介质的相互作用，以诱导流体上的电体力，并使流体运动。这种冲击提供了显著增强传热以及控制传热的能力。长期研究目标将是建立分析方法和设计指南，以促进这些新系统的广泛应用，以最大限度地发挥EHD效应的潜力。由此产生的知识将为HQP提供方法和工具，将现有的热管理和转换系统与这些急需的新技术相结合，将废热转化为可用的能源。
