A remarkably high heat flux can be obtained with a heat source of small temperature difference by generating a small amount of electrolytic hydrogen gas from a heating surface under nucleate boiling conditions. In order to elucidate the mechanisms involved in such a system and also in heat transfer in ordinary nucleate boiling, the diameter of escaping vapor bubble at the time of nucleate boiling under reduced pressure was investigated theoretically and experimentally. It was determined that an analytical model which considered the frequency of vapor bubble generation was able to explain relatively well the experimental values.
