| Outline of Final Research Achievements |
Measurements of cleaning processes due to bubble rising motion and numerical simulations for the bubble motion to investigate the mechanism of membrane cleaning. As a result, the following conclusions are obtained: (1) bubbles sliding on the membrane surface possess much larger cleaning efficiency compared to bubbles wobbling apart from the surface, (2) the cleaning efficiency does not increase even with increasing the gas flow rate for gas flow rates larger than a certain critical value, and (3) a numerical method based on the interface tracking method and GPGPU has been developed.
