Heat removal of more than 10MW/m^2 in heat flux has been required in high heat generation equipments in nuclear fusion reactor. In some condition of water subcooling and velocity, there appears an extraordinary high heat flux boiling in transition boiling region. This boiling regime is called micro-bubble emission boiling (MEB) because a lot of micro-bubbles are spouted from the heat transfer surface accompanying a huge sound. This study is aimed to obtain heat transfer performance of MEB in horizontal and vertical heated surfaces to parallel flow of subcooled water, comparing with CHF of this system. Three types of MEB with different heat transfer performance and bubble behavior are observed according to the flow velocity and liquid subcooling.
