Application of Digital Image Processing in Two-Phase Flow
A method for digital image processing and analysis of two-phase bubbly flow is presented. The procedure determines: bubble size distribution, shape and trajectory. The digital image processing and analysis of the dynamics behaviour of vapor bubbles in subcooled flow boiling in vertical annular tube are described. The procedure can be employed to determine: an overall average bubble diameter, bubble life time, interfacial area, and bubble trajectory. 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.
