| Outline of Final Research Achievements |
From visualization of reaction front, the progress of it was divided by the Atwood number and dimensionless reaction rate. For HCl-NaOH system, there were two progresses of the front with acute‐angled protuberances and without them, respectively. On the other hand, for CH3COOH-NaOH system, some semicylindrical protuberances were formed at the reaction front due to the generation of salt finger between sodium acetate aqueous solution and NaOH solution by using numerical simulation. The formation of the semicylindrical protuberances was also observed by the refractive index distribution due to Laser Speckle Method.
