摘要

Modulated(periodically non-uniform thickness)porous-layer coatings, as an example of capillary artery-evaporator systems, are experimentally shown to enhance the pool-boiling critical heat flux nearly three times over that of a plain surface. The modulation separates the liquid and vapor phases, thus reducing the liquid-vapor counterflow resistance adjacent to the surface. Theories are suggested for two independent mechanisms capable of causing the liquid choking that leads to the critical heat flux.
