초록

건축물의 환기성능 평가를 위한 모델링 과정에서 핵심 경계조건으로 활용되는 풍압계수는 통상 저층형 단일 건물에 대해서만 자료화되어 있어, 공동주택 단지와 같은 고층형 집합주택의 모델링 시에는 적용할 수 없다. 이에 본 연구에서는 CFD(Computational Fluid Dynamics)해석을 통해 건물의 배치 및 종횡비가 다른 판상형 공동주택에 대하여 풍향각에 따른 풍압계수의 특성을 분석하고 유형화함으로써 환기 모델링 시 참고할 수 있는 기초자료를 제시하였다. 풍향각 0도의 경우 가장 풍상측에 위치한 건물의 정면에서는 좌우가 반전된 S자 형태의 풍압계수 분포가 나타났으며, 최하층, 최상층 및 2개의 변곡점에 해당하는 풍압계수는 건물의 높이와 관계없이 비교적 근사한 값을 보였다. 저층부의 변곡점은 약 11m 높이에 형성되었으며, 고층부 변곡점의 높이는 건물의 높이에 비례하는 추세식을 통해 산출가능함을 확인하였다. 또한 풍향각 45도 조건을 제외하면 대부분의 조건에서 풍압계수의 평균값을 적용 가능함을 확인하였다.

In this study, basic data that can be referenced for ventilation modeling was presented by analyzing the characteristics of wind pressure coefficients(Cp) according to wind direction angles under conditions of different building layouts and aspect ratios through CFD (Computational Fluid Dynamics) analysis for flat-type apartment complexes. In the case of a wind direction angle of 0°, Cp distribution in the form of an inverted S-shape was shown on the front of the building located on the windward side. And Cp corresponding to the lowest floor, the uppermost floor, and the two inflection points showed relatively close values regardless of the height of the building. The inflection point of the low-rise part was formed at a height of about 11m, and the height of the high-rise part could be calculated through a trend formula proportional to the height of the building. It was confirmed that the averaged Cp value can be applied in most conditions except for the wind direction angle of 45 degrees.
