In order to study diffusion and chemical reaction structure, the authors tried to inject a small amount of Sodium Hydroxide Solution (NaOH) into water bath containing Hydrochloric Acid (HC1), and observe acid-base neutralization process using Phenolphthalein. The paper presents a plan of the system and a comparison between images of diffusion flames and the reacting liquid jets. The observation results show that the chemical reaction and diffusion process of a reactive liquid jet is similar to that of diffusion flame. Based on the similarity between the two phenomena, results with the reactive liquid jet suggests that the major NOx formation region exists at the vicinity of the head and tail of the jet flames.
