This paper presents results of the experimental study of the subcooled water boiling on the surface of the cylinder heater. The initial stages of formation of the developed nucleate boiling were investigated. The field temperature of heated liquid layers at the moment of bubble departure was described by numerical modelling at non-stationary condition. A high-speed digital video camera was used to capture the bubble dynamics. The experimental data on the bubble dynamics was compared with Prodanovic's and Song's models. A poor agreement between the predicted departure diameter and the experimental one was obtained for both of the models. © 2017 The Authors, published by EDP Sciences.
