- Abstract
A numerical simulation using Flow-3D software was conducted to study the characteristics of forced hydraulic jump. The purpose of this study is mainly to improve the efficiency of the stilling basin for increasing energy dissipation. The generated model is a spillway followed by a stilling basin that contains scattered baffle blocks as energy dissipators in different shapes and arrangements, placed in regular or staggered rows, and followed by a positive step at the same height. Sixty runs were considered, and each configuration of baffle blocks was tested under five values of discharge (80, 100, 120, 140, and 160 liters per second). The numerical results showed that the obstacles have a significant effect on improving the flow characteristics and increasing energy dissipation. The best case is installing seven rows of circular baffle blocks in a staggered way at equal distances in the stilling basin, and the relative energy loss ranges from 50% to 60% according to flow conditions.
