Client Profile

Leading tanker truck manufacturer from USA
Industry: Tanker Truck Manufacturing, USA

Objective.

Hitech conducted CFD analysis using VOF (Volume of Fluid) model to predict liquid sloshing in tanker truck and deliver design analysis backed insights to optimize the tank design and selecting optimum spacing of baffles – if used. Analysis was carried out with and without baffles in the tank in order to study, compare, and reduce sloshing effect while the truck is in constantly accelerated linear motion.

Challenges.

Hitech’s Solution.

CFD experts at Hitech predicted liquid sloshing in tanker truck by conducting CFD analysis using VOF (Volume of Fluid) model along with realizable k-epsilon turbulence model. Dynamic mesh was utilizedto capture oscillatory motion of the tank partially filled with water. Simulation was carried out for multiple tank rolling cases to capture water sloshing inside the enclosed rectangular tank. Results of the CFD simulation improved tank design by adding baffles and reduce the sloshing effect & ensured stability of the truck while in motion.
