| Outline of Final Research Achievements |
A new electricity generation system using a bubble column is proposed. In order to examine the feasibility of new electricity generation system, gas-liquid two-phase flow is studied using a bubble column of laboratory scale with a height of 5.5 m. The water superficial velocity increased with the air flow rate and submerge ratio. The highest value of the superficial velocity was 0.8 m/s at gas superficial velocity of 0.14 m/s. Rotation speed was linearly proposed to the water flow rate and maximum value was 280 rpm. This value is considered to be sufficiently high to drive the generator.
