Abstract

Bubble size is an important variable that determines the efficiency of air induced liquid mixing, which, due to its passive nature, is commonly used in processes involving radioactive species. In majority of cases, in air induced mixing devices used in radiochemical plants, air is introduced through top-submerged nozzles. This necessitates fundamental understanding of the phenomenon of bubble formation at top-submerged nozzles placed inside a liquid pool. In this study, a mathematical model is developed by carrying out force balance to estimate the diameter of the bubbles generated at the tip of a top-submerged nozzle submerged in a quiescent liquid. The model is validated with the experimental data. The parametric analysis carried out with the developed model provides detailed understanding of the effects of geometric, operating parameters and properties of the liquid medium on bubble formation phenomenon.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
