화재실과 경사 공간 사이에 위치하는 개구부에서 경사 공간을 고려한유량계수에 대한 수치해석적 연구 = Numerical Study on the Flow Coefficient Considering Inclined Space in the Opening between the Fire Room and Inclined Space

다국어 초록 (Multilingual Abstract)

In this study, a calculation model was constructed assuming the space from the fire room (basement floor) of the buildingto the ground floor through an inclined space. The effect of the inclination angle on the flow coefficient in the openingbetween the fire room and inclined space was investigated. The results showed that the flow coefficient at the opening wasmaximum around the angles of 20° 30° and then decreased. In addition, it was confirmed that Equation (8) expressed –the relationship between the flow coefficient and inclination angle.

본 연구에서는 화재실(=지하층)에서부터 경사 공간을 통하여 외부로 이어지는 공간을 상정한 계산 모델을 이용하여 화재실과 경사 공간 사이에 위치하는 개구부의 유량계수에 경사 공간의 경사 각도가 미치는 영향에 대하여 파악하였다. 그 결과, 개구부에서의 유량계수는 경사각도 20°∼30° 부근에서 최고값에 도달하였고 그 이후부터는 감소하였으며, 경사 각도에 대하여 식(8)과 같은 관계를 확인할 수 있었다.
