Abstract
This paper focused on numerical methods to investigate the flow conditions in sediment tanks with the cavity. The model used for simulation is based on experimental devices, for identifying the effect of cavity on sediment efficiency, the model with no cavity and models with different height of cavity will be investigated. With the effect of cavity, the flow condition in sediment tank would be different, which is the dominate force of the performance of sediment tank, which can also result in the alteration of sediment efficiency. With the change of roughness of boundary, alteration will also be made in sediment transport. With the use of user-defined function in fluent codes, the investigation of different boundary conditions was allowed. The research in this paper mainly aims at promoting the performance of sediment tanks and investigating the factor that will affect sediment transport in tanks.
