Experiments on effective microbubble generation usuing a fine pores system

Abstract

Microbubble was generated using a fine pore system by flowing oxygen and water solution simultaneously.
The experimental condition was varied in concentration and kind of solution for finding more effective generation. Solutions of NaCl, cane sugar and ethyl alcohol of 0.1 to 0.9 mol/l were used. In case of higher concentration of ethyl alcohol solution exhibited the most effective microbubble generation.
Generation mechanism was discussed based on the physical and chemical characteristics of solution.
