摘要

To clarify the heat transfer mechanisms in microgravity nucleate boiling, the measure- ment of the microlayer thickness underneath primary bubbles generated at the base of a coalesced bubble was attempted. The transient heat conduction model was developed to predict the change of microlayer thickness and of corresponding local heat flux value in one growth period of the primary bubble. The predicted heat flux agreed well with the value obtained from the heat conduction across the heating surface substrate.
