Abstract

The goal of this study was to develop a venturi-type air bubble generator with a porous material throat. Using the two-phase multi-flow CFD analysis for the venturi tube, researchers determined the optimal design of major dimensions, such as the venturi throat length and diameter, in order to control the performance of the air bubble supply through the porous material throat in a venturi tube. Researchers then determined the relationship between the flow rate of supply water and the major design dimensions of the venturi-type air generator for maximizing the performance of the air bubble supply through the porous material throat in a venturi tube.

본 연구는 다공성 재질의 목을 가진 벤츄리관 공기방울 발생장치의 설계를 위해 수행되었다. 주어진 공급 유량 조건 하에서 다공성 재질을 통해 공급되는 공기방울의 공급 성능 최대화를 위한 벤츄리관의 길이와 직경을 결정하기 위해 2상 전산유동해석에 기초한 최적화 설계를 수행하였다. 이러한 일련의 연구 수행 결과를 통해 다공성 재질을 통해 공급되는 공기방울의 공급 성능 최대화를 위한 공급유량과 이들 설계변수들 관계를 규명하였다.
