Abstract
This paper analyzes fluid dynamic in dam spillway with 4.9�m of sector gate opening. Hydraulic parameters that were determined in this study are pressure, velocity and streamline. A three-dimensional (3D) computational fluid dynamics (CFD) model of dam spillway structure and boundary condition were developed using ANSYS FLUENT. CFD model results show that the highest velocity value which is 14.8�m/s and the largest hydraulic jump occur is at the middle between two energy dissipators of the dam spillway. Hydraulic jump type that occurred which is oscillating jump is determined by the Froude value of 2.988. The high velocity contributes to the large hydraulic jump that may lead to damaging effects to stilling basin surface at downstream. Structural integrity for sustainability of spillway should be ensured for future mitigation. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
