A proper observation and characterization of wall nucleation phenomena in a forced convective boiling system

Additionally, an image analysis method was developed to efficiently and accurately extract the quantitative information of fundamental bubble parameters from the experimental images of boiling bubbles. The performance of this method was tested in subcooled boiling flow circumstances, and it seems promising as a means of analyzing the vast number of images required to satisfy the high statistical demands to characterize wall nucleation features. The experimental findings and discussions in the present study will provide valuable guidance towards the proper investigation of the wall nucleation phenomena in a subcooled flow boiling system or, more generally, in a forced convective boiling system.
