A basic characteristic of the reacting mixing flow was investigated. The reaction between an ammonia solution [0.1mol/L] and an acetic acid solution [0.1mol/L], which produced ammonia acetic acid solution, was investigated in terms of the effect on the fluid-fluid interface of mixing flow, relative to fluids that did not react. The reaction between these solutions was negligibly exothermic, and the density and other thermo-physical properties were also not much different. The chemical reaction would only affect the mixing flow and the interfacial stability, while turbulence would enhance the chemical reaction. Two experiments were performed. In the first experiment, the mixing flow of an upward round jet and an upward ambient flow was studied. In the second experiment, the interfacial instability was investigated under parallel flow conditions in the rectangular tank. The acidic and alkaline solutions were flowed separately down individual rectangular channel 30 mm in w |
