This proposal is concerned with modeling of the thermal-fluid performance characteristics of complex internal flow systems and development of new technologies for next generation applications. Simple and complex flow architecture is found in compact heat transfer devices for refrigeration, electronics cooling, automotive cooling, solar heating, and in countless other process flows. Complex flows are also found in new compact energy devices such as fuel cells, micro fluidic "lab on chip" devices, micro-systems, MEMS, and other next generation technologies. There is a need for fundamental study, both theoretical and experimental, to better ascertain the performance characteristics and to develop predictive models for use in specialized or generic simulation codes. This proposal aims to study several fundamental problems now facing designers of systems utilizing compact and micro-flow architecture. Three key focus areas have been chosen for this grant cycle. These include: single and two phase flow in micro- and mini-channels, optimal design of compact and enhanced heat transfer devices, and experimental and theoretical modelling of multiphase and non-Newtonian flows. As part of this work, we also expect that new cooling concepts will be developed with working prototypes being constructed to demonstrate feasibility.These improved concepts will be smaller and more efficient than their predecessors.

该提案涉及复杂内部流动系统的热流体性能特征建模以及下一代应用新技术的开发。简单和复杂的流程架构存在于用于制冷、电子冷却、汽车冷却、太阳能加热以及无数其他工艺流程的紧凑型传热设备中。复杂的流动也存在于新型紧凑型能源设备中，例如燃料电池、微流体“芯片实验室”设备、微系统、MEMS 和其他下一代技术。需要进行理论和实验方面的基础研究，以更好地确定性能特征并开发用于专用或通用仿真代码的预测模型。该提案旨在研究利用紧凑和微流架构的系统设计者现在面临的几个基本问​​题。本资助周期选定了三个关键重点领域。其中包括：微通道和迷你通道中的单相流和两相流、紧凑型和增强型传热装置的优化设计以及多相流和非牛顿流的实验和理论建模。作为这项工作的一部分，我们还期望开发新的冷却概念，并构建工作原型来证明可行性。这些改进的概念将比其前身更小、更高效。
