摘要：
Experiments are performed to understand the effects of surface orientation on the pool boiling characteristics of a highly wetting fluid from a flush-mounted microporous-enhanced square heater. Micro-porous enhancement was achieved by applying copper and aluminum particle coatings to the heater surfaces. Effects of heater orientation on CHF and nucleate boiling heat transfer for uncoated and coated surfaces are compared. A correlation is developed to predict the heater orientation effect on CHF for those surfaces.
