직사각형 맨홀의 내부형상변화에 따른 흐름특성 분석
An Analysis of Flow Characteristics with Changing the Inside Shapes in Square Manhole
- 발행 : 2007.02.22
초록
In storm sewer networks a lot of manholes are installed to maintain and connect a sewer of urban area. There are some shapes of manhole such as circular type, square type, and so on. Square shape manholes are installed to connect the large diameter drainage pipes in general and have lager head losses than circular one. Consequently, it is important to analyze the head losses in square manhole because the head losses in square manhole are much bigger than the friction losses in pipes. Hydraulic experimental apparatus which can be changed the inside shape in square manhole was installed for this study. The experimental discharge was
