SGER: Effects of a Porous Boundary on Convective Condensation in Small Diameter/Micro-Channels

本文旨在资助微通道内两相流传热的创新性探索性研究。微通道在电子冷却和高热流密度的微型热交换器中有着广泛的应用。新的想法是利用一个多孔的边界作为灯芯来帮助冷凝液的去除。现有的关于包含较大通道的多孔介质中的热和流体流动的知识并不适用，因为作用在流体上的力不随物理尺寸线性缩放。首席研究员建议进行实验，以研究冷凝两相流动的物理行为，并确定多孔边界对传热的影响。

ABSTRACT This proposal is to fund innovative exploratory research on two-phase flow heat transfer in microchannels. Microchannels have applications in electronics cooling and miniature heat exchangers involving high heat fluxes. The new idea is to employ a porous boundary to act as a wick to assist in the removal of condensate. Existing knowledge about heat and fluid flow in porous media involving larger channels does not applied because the forces acting on the fluid do not scale linearly with the physical dimensions. The Principal Investigator proposes to conduct experiments to study the physics of condensing two-phase flow behavior and determine the effects of the porous boundary on heat transfer.
