Bubble departure diameter at transient heat release

... DOI: 10.1051/matecconf/201711508014 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 of the wall thermal boundary layer at the initial stage of the nucleate boiling

... experimental study of the water nucleate boiling on the surface of the cylinder heater. We investigated the initial stage of formation of the thermal boundary layer with rise and departure of bubbles with the departure diameter of 50 μm. To build the field temperature at the moment prior to the start of boiling, we used a numerical model implemented in the COMSOL multiphysics software. The experimental data on bubbles dynamics was compared to the numerical calculation of the temperature, and the relationship ...
