Abstract: A new analytical model of longitudinal liquid sloshing is developed using the Navier-Stokes theoretical equations and the principle of work and energy for tank models with lateral orifice baffles. The analyses are performed under varying magnitudes of longitudinal accelerations of the tank, and using two different fills. The results obtained are compared with the simulation results obtained using the full complex Navier-Stokes equations. The comparison is presented in terms of mean and peak of longitudinal and vertical shift of the centre-of-mass coordinates and also in terms of longitudinal pressure force and mass moment inertia variations.

Keywords: tank vehicles; orifice baffles; pressure force; braking force; sloshing impact; longitudinal liquid sloshing; modelling; lateral orifice baffles; simulation; Navier-Stokes equations; mass moment inertia.
