| Outline of Final Research Achievements |
In a steel refining process, microbubbles are well known to be an important role for promoting a chemical reaction. However, the state of gas jet (i.e., lots of microbubbles or a gas tube penetrating out of the molten iron bath) injected into a reactor from a nozzle cannot be observed directly because of a molten iron being opaque. The present study attempted to establish a measurement technique for acoustic evaluation of occurrence of a microbubble generation/detachment and Rayleigh jet phenomenon. This experiment was successfully carried out in a water-model experiment, whose the value of the kinematic viscosity is almost identical with that of a molten iron, by synchronizing the recorded results between a hydrophone and a high-speed photograph.
