In this study, the effects of building-roof cooling on scalar dispersion in three-dimensional street canyons are investigated using a computational fluid dynamics (CFD) model. For this, surface temperature of building roof is systematically changed and non-reactive pollutants are released from stree...

비반응성 오염물질의 확산 특성을 분석하기 위해 사용한 것은? | 비반응성 오염물질의 확산 특성을 분석하기 위하여, 무차원화한 농도를 사용하였다. 무차원화 방법은 Pavageau and Schatzmann (1999)이 제안한 방법을 따랐고, 무차원 농도(K)는 다음과 같이 표현된다. | |
본 연구의 결과가 도시 지역의 기후 및 대기질을 예측함에 있어서 유용한 정보를 제공할 것으로 기대하는 이유는? | 결론적으로, 본 연구를 통하여 옥상 녹화는 도시 협곡 내 흐름을 강화시키고, 도시 협곡 기온과 대기 오염물질 농도를 감소시켰다. 이 연구 결과는, 향후, 도시 개발 및 녹지 조성시, 건물 옥상 온도 변화에 따른 도시 지역의 기후 및 대기질을 예측함에 있어서 유용한 정보를 제공할 것으로 기대된다. | |
