Calculating hydrostatic pressure on radial gate of Hang Bang barrier

Abstract

The objective of this study is to model the hydrostatic pressure on the radial gate of Hang Bang Barrier in the Can Tho, Vietnam - Enhancing Urban Resilience Project using a three dimensional CFD program called Flow-3D. The formulas for calculating hydrostatic pressure on radial gates were also used in this study. Input data was collected from design document of the Hang Bang barrier. The model results from Flow-3D showed a good match with the calculated results using the formulas. It indicates that Flow-3D can be used to model hydrostatic pressure induced on radial gates.
