エアレーションにより生ずる流れの数値解析

Abstract

This paper deals with the mathematical procedure of simulation analysis for the fluid flowinduced by aerations in thermally stratified waters. The previous studies for the air-bubble systemshave been reviewed and the mathematical model for the air-bubble plumes is newly developed. Thenumerical simulation technique for the mathematical model is developed and some applications ofthe technique to the air-bubble plumes in thermally stratified waters are also made. Furthermore, the mathematical procedure of simulation analysis for the horizontal flow induced by air-bubbleplumes is developed and examined with some case studies.
