Abstract
The objective of this thesis was to develop an ICFD finite element model of a partially filled deformable container suitable for impact scenarios. This model will be later incorporated into the existing TL-6 vehicle model, which is a tractor-tank trailer vehicle model. Previous finite element fluid models for the TL-6 vehicle used an elastic fluid model, which could not predict the fluid behavior correctly.
A study was conducted on the ICFD modeling and an improved ICFD model has been developed using the LS-DYNA, a finite element analysis software. Different properties and parameters of the fluid and the container were adopted from the previous models and scientific research publications.
The ICFD model was a cylindrical capsule of 2 m long and 1 m wide, containing a ballast of 284 gallons of water. Impact condition of 20 m/s speed to a rigid wall was simulated. The model was able to achieve the fluid sloshing behavior ensuring no leakage of fluids from the model. There was no warpage or shooting of elements, the model was stable and robust. Therefore, it was considered an improvement to the previous elastic models used in the TL-6 vehicle model.
