A phenomenon of subcooled boiling with a bubble condensation is thermal nonequilibrium, and to bring out complicated behavior in a conventional study. But it was clear that the result does not accord with the conventional experimental data and theory, which be adapted to two-fluid model or three-fluid model in forced-convection subcooled boiling. It is the fact that the characteristic of bubble in forced-convection subcooled boiling is not made enough clear. In this study, the object find out that the condensation of bubble in the low quality region gives the two-phase flow, which is photographed by using high speed camera. As a result, the bubble diameter is changed the flow condition and the influence of heat, and the changing of bubble diameter with condensation and a term of condensing bubble change the flow of down stream.
