| Abstract: | In this study, we performed numerical simulations of nucleate boiling to evaluate the formation of microlayer, which isthin liquid film forming on the heated solid surface. To evaluate the formation condition of microlayer of FC-72, numerical simulations were performed for three wall superheat conditions of 5 K, 10 K, and 15 K. As the result, the microlayer is formed under the wall superheat of 15 K. In addition, the influence of microlayer formation on the heat transfer was significant, indicating that the wall surface temperature decreased the most when the superheat was 15 K. |
