Abstract
In the second report, the extraction technique of the bubble boundary described in the first report is applied to analyze the subcooled flow boiling in the vertical annular tube. The procedure determines bubble size and shape, interfacial area, information about void formation, bubble growth or collapse, position and velocity of bubbles, bubble life time and bubble trajectory for particular condition. These parameters are of fundamental importance in two fluid model formulation, especially in relation to the rational design and effective operation of facilities in the energy power systems and in various industrial processes.
