Abstract
On thermal facilities, miniaturization is progressing. In the case of boiling equipments, flush evaporation phenomenon makes the difficulty on the miniaturization due to the boiling bubble size. If the usual heater is used, boiling bubble size remains constant, which is not desired for the miniature thermal equipments. Further, these boiling equipments are frequently operated under low-pressure condition, which affects oppositely to the boiling bubble size. Therefore, it oust be develop the boiling size reducing method especially for low-pressure condition. In this study, reeled by thread method was proposed and experimentally investigated. The results show that the method is useful to reduce the boiling bubble size, however, the method increases the heater surface temperature.
