| Outline of Final Research Achievements |
This study describes the results of dielectric liquid pool boiling experiments on a polished copper wall with the application of an electric field. Then, micro-structured surfaces were used as the boiling surface. Finally, the combination of the application of electric filed and the micro-structured surface was tested. In addition, the effect of the electric filed and the micro-structured surface on critical heat flux (CHF) were analytically investigated. The maximum CHF with the application of electric field was 4 times greater than that for the pool boiling. The CHF were increased by the micro-structured surface, and showed maximally 40 % higher than the CHF for the polished surface. The combined effects of the electric filed and the micro-structured surface increased the CHF significantly, which was 4.5 times greater than that for the pool boiling. The combined effect on CHF was sufficiently detected by the analysis results.
