Abstract

Methane emission impact the environment in various ways and degrade the living conditions of citizens due to the odor. In order to prepare foundational information for response measures related to methane emissions, numerous studies are being conducted to understand the behavior of methane's velocity distribution. However, most of these studies are based on artificial bubbles formed through pressure, and research on velocity distribution itself is relatively scarce. Therefore, this study aims to analyze the velocity distribution of bubbles that naturally occur through BMP tests. For this purpose, samples used in BMP tests were prepared, and the moment bubbles were formed was captured and recorded. Subsequently, using an In-house Post Image Analysis Tool, image analysis was conducted and velocity data by height were extracted. Through nonlinear regression analysis and dimensional analysis, a simplified generalized formula was presented. This simplified model, utilizing only physical indicators, offers the advantage of easy use by general managers. If this research is extended to analyze bubble behavior under various environmental conditions and to include other types of greenhouse gases, it is expected to contribute to more precise environmental management and pollution prevention strategies.

수체에서 발생하는 메탄의 용출은 환경에 다양한 영향을 미치며 악취로 인해 시민들의 생활환경을 저하시킨다. 메탄 용출 관련 대응책에 관한 기초 정보를 마련하기 위하여 메탄의 속도분포 거동을 이해하기 위한 다양한 연구가 수행되어지고 있으나 압력을 통해 형성된 인공기포 기반의 연구가 대부분이며 속도분포에 관한 연구는 상대적으로 미비하다. 이에 본 연구는 BMP test를 통해 자연적으로 발생된 기포를 기반으로 기포의 속도분포에 관한 분석을 진행하고자 한다. 이를 위해 BMP test에 사용되는 시료를 제작하였으며 기포가 생성되는 순간을 포착하여 녹화를 진행하였다. 이후 In-house Post Image Analysis Tool을 활용하여 이미지 분석을 진행한 후 높이별 속도데이터를 추출하였으며 비선형회귀분석과 차원해석을 통해 간소화된 일반화식을 제시하였다. 이 간소화 모델은 물리적 지표만을 활용하여 일반 관리자들이 쉽게 사용할 수 있는 장점이 있다. 향후 다양한 환경 조건에서의 기포 거동 분석 및 다른 유형의 온실가스에 대한 연구로 확장된다면 더욱 정밀한 환경관리 및 오염 방지 전략을 수립하는데 기여할 수 있을것으로 기대된다.
