CFD Analysis on Different Filling Volume Capacity and Fluid Density for Flexitank Application

When it comes to the structural design of flexitanks used for freight transportation, liquid sloshing is a crucial subject of concern. However, with consideration of the flexitank shape, there is no specific capacity value that can be used as a guide for filling the liquid inside it. This phenomeno...
