Pool-Boiling Liquid-Checking Limits Within and Above Modulated Porous-Layer Coating

调制多孔层涂层将对核态沸腾和池沸腾临界热流密度产生强化作用。 将通过建模和实验来检查、描述和优化增强的上限。 将使用物理学和理论相结合的方法。 假定液体输送到表面的阻塞极限，即，临界热通量通过蒸汽去除中的流体动力学不稳定性或通过多孔层涂层的固-液粘滞阻力（以较小者为准）而达到。 预计这项研究的结果将产生一个多孔层涂层，表现出optimalpool沸腾传热，并有助于在高通量表面的进步和设计和制造的表面微结构的传热目的。

The enhancement of nucleate-boiling and the critical heat flux in pool boiling will be made using modulated porous-layer coating. The upper limits for enhancement will be examined, described, and optimized through modeling and experiments. A combination of empiricism and theory will be used. It is postulated that the choking limit of liquid delivery to the surface, i.e., the critical heat flux, is reached either by the hydrodynamic instability in the vapor removal, or by the solid-liquid viscous drag the porous-layer coating, whichever is smaller. It is expected that the results of this investigation will produce a porous-layer coating that exhibits optimalpool boiling heat transfer, and contribution to advances in high flux surfaces and to the design and fabrication of surface micro-structures for heat transfer purposes.
