Computational analysis dynamics fluid of flow in dam using COMSOL Multiphysics

Abstract One way to utilize river flows in Indonesia is make a dam get benefits various fields. The flow that enters the and which will again makes causes fluid dynamics. dynamics occur dams produce several events such as precipitation, turbulence, so on. To see how is, this study simulation was carried out by making model followed analysis of model. Then it be solved finite element method. In its completion, COMSOL Multiphysics program used applies method results simulations. obtained using mesh transfer Where displacement speed surface velocity when entering, solution equation uses on node, Navier Stokes substituting mesh. at an interval approximately 3 seconds with 0.7 m/s turbulence where maximum 0.4 m/s. As result, if there are other elements than water, cause mixing substances middle then precipitation occur. next study, different models have faster rate.
