Applying Imaging Technique to Investigate Effects of Solute Concentrations and Gas Injection Rates on Gas Bubble Generation

Abstract: This work investigated the bubble size variation under various aqueous conditions, including saline and surfactant solutions, with different gas injection rates using a commercial bubble analyzer. The results show that salt and surfactant can minimize bubble size with increasing solute concentration, and the surfactant outperforms salt. In addition, the critical coalescence concentrations (CCC) of salt and surfactant could be determined at 20 g/l and 20 mg/l, respectively, over which bubble mean size cannot be… Show more

“…Subsequently, an image-adjust plugin in ImageJ 1.53c was utilized to convert the grayscale image into a binary image, containing only pore space and soil. Manual thresholding was performed to determine the segmentation threshold between the pore and background [47]. This threshold was adjusted by comparing the binarized pore image with the original pore image to maximize the accuracy and conformity of the segmentation.…”
