摘要 | The technology of image enhancement has been proved to be very effective and powerful in the quantification of bubbling regime, heat transfer performance and mixing efficiency in a direct contact boiling heat transfer process. In the present work, this image analysis technique was combined with some statistical hypothesis-testing tools including Kolmogorov-Smirnov test and chi-square test in order to compute the p-values for bubble images comparison. It was indicated that the employed hypothesis-testing tools are effective in testing whether the every two bubble images gray distribution have the same or close gray distribution. Specially, the different experimental cases with the same Betti numbers can be identified by using our methods. p-value represents a meaningful parameter to study the mixing transient. Testing statistics can be used to quantify evolution of bubble swarms in direct-contact boiling heat transfer process. Results obtained from the real experiment indicate that the inflection point of observed values of testing statistics is roughly equal to mixing time, which is the main merit of the employed tools. © 2016 Elsevier Ltd |
