| Outline of Final Research Achievements |
We proposed a technique to enhance the critical heat flux (CHF) action and (2) vapor escape channels from the top surface due to gravity. In this study, we especially focused on (2) the liquid supply through vapor escape channels from the top surface due to gravity. Based on the results, the following conclusions were obtained: In the high heat flux region, the liquid supplied by capillary action was shown to be the dominant factor leading to the CHF enhancement in saturated pool boiling, and the calculated CHF by the capillary limit model were found to be in good agreement with the CHF obtained from the experiments extracting only the effect of capillarity. Moreover, the new CHF model considering the two liquid supply mechanism as stated above was proposed to predict the CHF by honeycomb porous plate in a saturated pool boiling.
