基于数字图像处理的掺气水流气泡分布研究
Digital image processing based study on bubble distribution of aerated flow
摘要
Abstract
Through laboratory study and based on high-speed digital video camera, a software for analysis on bubble of aerated flow is developed herein incorporated with the advanced VC programming technique for trial and exploration made on the combination between the image processing technique and the study on the actual measurement of the two-phase flow ( air-water) , and then a digital image processing method for automatically recognizing the bubble in the two-phase flow is put forward as well. This study lays a better basis for the further study to be made on the application of image processing technique to the measurement of flow field, especially high-speed two phase flow field in the days to come; which has a higher applicable value for enhancing the level and accuracy of the measurement on the aeration concentration, improving the level of hydraulic model test and meeting the requirement from the engineering design concerned.关键词
