Local wall temperatures and liquid phase temperature field during isolated bubble nucleate boiling were measured with the thin film thermocouples on the MEMS thermal sensor and the interferometry, respectively. Through the heat transfer analysis with the measured local wall temperature, it was found that the microlayer dominantly contributes to the wall heat transfer during nucleate boiling of water, and the evaporation from the superheated layer around the bubble has an important role in the bubble growth. The interferometric method visualized flow of the thermal field around the bubble, such as the thermal boundary layer lifted up by the bubble growth and the hot wake accompanied by the rising bubble. However, the interface heat transfer was not able to be measured due to shortage of the spatial resolution of the used interferometer system.
