| Research Abstract |
This research aims at establishing a method which performs absorption of carbon dioxide gas and transportation of dissolved gas and carbon-dioxide adsorption particles by turbulent water flow in a vertical duct.
It was found that the volume of carbon dioxide bubbles reduced with time by the absorption of turbulent flow. The images of the collision of carbon dioxide bubbles and zeolite particles were captured, and the motion of the particles was analyzed. A non-contact measurement of the temperature distribution in the circumference of the carbon dioxide bubbles was tested. The decrease in the dissolution rate of carbon dioxide in bubbles to ambient water with time was predicted by using a phase-field method.
