Abstract

Dynamics of liquid sloshing in compartmented and baffled rectangular road containers for uniform braking and steady cornering manoeuvres is presented and discussed. Analytical steady-state and numerical transient solutions are given in terms of liquid height, forces and overturning moments exerted by the liquid on the container body. The influence of the number of separating walls, size and location of orifices in the separating walls is studied. The transient response of the liquid is obtained by a numerical solution of the incompressible 2-D Navier-Stokes, continuity, and the free-surface differential equations. A modification to the Marker-and-Cell technique, with special attention to boundary conditions and maintaining the mass conservation of the flow through a correction for the liquid height, is adopted as a method of numerical solution. This paper, as far as the authors know, is the first reported study on the complicated sloshing phenomena in containers with separating walls, based on the solution of the fully nonlinear hydrodynamic equations. The methodology adopted allows one to predict sloshing loads more accurately and for a wider range of input parameters than linear theories can do.
