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

采用调制多孔层涂层可以提高核沸腾和池沸腾的临界热流密度。增强的上限将通过建模和实验进行检查、描述和优化。将使用经验主义和理论相结合的方法。假设液体输送到表面的窒息极限，即临界热流密度，要么是由蒸汽去除过程中的流体动力不稳定性达到的，要么是由多孔层涂层的固液粘滞阻力达到的，取其小者。预计本研究的结果将产生具有最佳池沸腾传热的多孔层涂层，并对高通量表面的发展以及用于传热目的的表面微结构的设计和制造做出贡献。

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.
