Fluid/structure interaction study on the variation of radial gate’s gap height in dam

Through fluid/structure interaction (FSI) simulation and experimental work on a scaled-down dam model, the influence of radial gate height to the force exerted to the gate wall during water flow is studied. Both numerical and experimental findings gave results of great consensus, with their deviation not exceeding 14.66%. The water flow across the radial gate of the dam is visualized as modelled based on volume of fluid (VOF) scheme. It is found that the force exerted by water flow on the gate wall is the highest with intermediate gap height of 10 mm as compared to 8 mm and 10 mm.
