Abstract
Focusing on the heat transfer mechanism of the MEB we are trying to express the heat transfer characteristics of subcooling boiling based on the microlayer model. This paper presents an estimation of bubble-formation and condensation period on the heating surface with high-superheat under the larger subcooling conditions. The heat transfer rate is estimated for higher heat flux than the CHF and compared to the experimental data for wire heating. The comparison indicates that there is a possibility to express the heat transfer of MEB by the microlayer model for subcool boiling.
