Robust modelling of complex internal flows

拟议的研究涉及复杂内部流动的实验和分析建模。同时考虑了流体流动和热阻。复杂的内部流动在工程系统中比比皆是。这些技术包括但不限于：紧凑型热交换器、强化的换热应用、复杂的内部流动结构(设计的多孔结构)、微流体系统、多孔介质、电子冷却系统以及采用膜技术的系统。特别是，这些系统的流体动力学和换热特性往往因两相流动和/或非牛顿流体行为而变得更加复杂。该提案将侧重于开发稳健的模型，以促进先进能源系统的热-流体设计，并通过建立最优流动结构来优化这些能源系统，从而最大限度地减少流体流动和热阻。这项研究涉及分析、数值和实验方法。本提案中与紧凑系统建模有关的一些研究问题是该领域行业需求的直接结果。最后，通过研究产生的新设计，可能实现与紧凑型和新型换热设备有关的潜在知识产权。

The proposed research deals with the experimental and analytical modelling of complex internal flows. Both fluid flow and thermal resistance are considered. Complex internal flows abound in engineering systems. These include but are not limited to: compact heat exchangers, enhanced heat transfer applications, complex internal flow architecture (designed porous structures), micro-fluidic systems, porous media, electronics cooling systems, and systems utilizing membrane technologies. In particular, the fluid dynamics and heat transfer characteristics of these systems is often further complicated by two phase flow and/or non-Newtonian fluid behaviour. The proposal will focus on the development of robust models to facilitate thermal-fluid design of advanced energy systems and on the optimization of these energy systems by means of establishing the best flow architecture which minimizes fluid flow and thermal resistance. The research involves analytical, numerical, and experimental methods. A number of the research issues in this proposal related to compact system modelling are a direct result of industry needs in this field. Finally potential intellectual property pertaining to compact and novel heat transfer devices may be realized with new designs emerging from the research.
