Development of electrohydrodynamic two-phase heat exchanger and thermal management technologies

热能转换与管理是影响汽车、燃料电池、航空航天、废热回收等应用领域发展的核心技术。两相热管理系统需要精确地控制温度，并最大限度地减少单位能量消耗系统的重量/尺寸。然而，可靠性、设计预测能力和瞬时控制并不容易获得，特别是在热交换器中。因此，需要分析能力来协助设计、开发和优化先进的热管理系统。拟议研究的目的是发展“智能”换热器设计方面的专业知识，并建立电流体动力学(EHD)作为智能控制的机制。EHD提供了根据施加的电压条件控制换热器和系统性能的能力。

Thermal energy conversion and management is a core technology that can strongly affect the advancement of applications including automotive, fuel cell, aerospace and waste heat recovery. Two-phase thermal management systems are required to precisely control temperature and minimize weight/size of the system per unit energy rejected. The reliability, predictive capability for design and transient control, however, are not readily available, especially in heat exchangers. Analysis capabilities are therefore required to assist in the design, development and optimization of advanced thermal management systems. The purpose of the proposed research is to develop expertise in 'smart' heat exchanger design and establish electrohydrodynamics (EHD) as the mechanism of intelligent control. EHD provides the ability to control heat exchanger and system preformance based on applied voltage conditions.
