To enable a virtual design and optimization process of partially filled coolant tanks a reliable numerical approach is needed to predict the liquid and gas two phase flow inside the tanks. In this study numerical results are validated by experimental data to examine the suitability of the method for the tank design process. The liquid motion inside the tanks can be described as sloshing with high amplitude, off-resonant roll excitation and was examined using a homogeneous multiphase model and VOF interface capturing approach as well as an experimental setup including piezoelectric pressure sensors and qualitative observation of the free surface. The effect of two vertical baffles on the maximum pressure and the position of phase interface was determined. The comparison between the computational and experimental results reveals that the numerical model tends to under predict the experimental peak pressures but resolves the liquid surface in close agreement with the experiments.
