Comparison of two analysis methods on bubble size distribution

The object of this work was to analyze foam bubbles' diameter distribution. Firstly, Rosin-Rammler distribution function was used in bubble size analysis in some studies. This Rosin-Rammler distribution function should be modified to fit foam bubbles distribution curve. Secondly, coefficient of variation value was introduced in our study. This analysis method could be carried out directly without any modification. Thirdly, these two methods were compared whose characteristics were analyzed. Both analysis methods were effective to analyze foam bubbles figures with relatively obvious difference. (paper)
