| description | In this paper the flow characteristics of stormwater are analyzed as it travels from a roof gutter down-pipe and
the turbulent flow generated on entering an individual lot on-site stormwater detention (OSD) unit beneath a residential carport. Comparison was made between a full-scale model and computational fluid dynamic (CFD)
simulations to determine the flow characteristics. These modular tanks with multi-unit chambers can capture
the roof run-off from a 15-minute, 10-year return period storm. The results from the physical and CFD models
matched well, suggesting that turbulent flow occurs when stormwater is directed to an individual lot stormwater
detention tank. However, turbulence in the OSD was concentrated around the inlet, after which the pattern changed from turbulent to laminar flow. This work implies that the use of modular underground storage tanks is
practical for managing stormwater from a roof. |
