Analysis of Hydrodynamic Performance in Flexitank Applications with Varying Strap Configurations Using CFD

Abstract

Liquid sloshing is a fundamental challenge in the structural design of
flexitank used for liquid transportation. Thus, flexitank is one of the
alternative ways for transporting the fluid package. However, there are
some cases reported by industry regarding the leakage of the flexitank
during transportation. The purpose of this study is to analysis of
hydrodynamic performance in flexitank application with varying straps
configurations using CFD software which is Ansys Software. For the
geometry of flexitak, Blender Software are used because it make the
model more 3D. In this study, the straps act like a baffle in the ISO tank.
There are several types of straps configurations in this study which are
the number of straps and depths of straps likes one strap, two straps
and three straps for the number of straps, while the depts of straps are
1/3, 1/2 and 2/3 of height the flexitank. By simulating these
configurations, the research aims to identify optimal designs that
minimize sloshing, improve pressure management, and reduce wall
shear stress. The study provides a comprehensive understanding of
how strap placement influences hydrodynamic forces, contributing to
the development of safer and more efficient flexitank systems for liquid
transportation.
