“…The size and location effects of a baffle orifice on the sloshing has been reported in only two studies devoted rectangular Popov et al [1] and generic Guorong and Rakheja [2] cross-section tanks. It should be noted that anti-slosh properties of baffle designs have been investigated through laboratory experiments by using small size tanks of different geometry Lloyd et al [3].…”

In this paper we consider vibrations of the baffled elastic fuel tank partially filled with a liquid. The compound shell was a simplified model of a fuel tank. The shell is considered to be thin and the Kirchhoff-Love linear theory hypotheses are applied. The liquid is supposed to be an ideal and incompressible one and its flow introduced by the vibrations of a shell is irrotational. The problem of the fluid-structure interaction was solved using the reduced boundary and finite element methods. The tank structure was modeled by the FEM and the liquid sloshing in a fluid domain was described by using the multi-domain BEM. The rigid and elastic baffled tanks of different forms were considered. The dependencies of frequencies via the filling level were obtained numerically for vibrations of the fluid-filled tanks with and without baffles. Keywords: baffles, fluid-structure interaction, free vibrations, liquid sloshing, multi-domain boundary element method, systems of singular integral equations.

“…These frequencies may lie in the vicinity of the steering frequency and the rotational modes of the sprung mass, and could lead to resonant oscillations. It has been further shown that the magnitudes of destabilizing forces and moments during the transient slosh are significantly higher than those attributed to steady-state or quasi-static slosh [4,6,11].…”

“…The transient fluid slosh analyses have been increasingly conducted using the computational fluid dynamics (CFD) methods based on the Navier-Stokes solvers coupled with the Volume-of-Fluid (VOF) technique. These numerical approaches are known to be effective for simulating large-amplitude fluid slosh, under time-varying manoeuvre-induced accelerations [5,11,16,17]. Only limited applications of the CFD methods, however, could be found for three-dimensional slosh analyses of baffled highway tanks.…”

“…The effect of size and location of baffle orifice on the slosh has been reported in only two studies involving rectangular [11] and a generic [4] cross-section tank. Popov et al [11] studied the effect of size and location of the orifice of a transverse baffle using a 2-dimensional scaled rectangular tank model, and concluded that an orifice opening equal to 5% of the baffle area would yield a 29% increase in the peak overturning moment for a fill depth ratio of 70%, when compared to that caused by tank with a separating wall.…”

Comparable magnitudes of slosh forces and moments, however, have been reported for orifice opening ranging from 8 to 20% of the cross-section area [4].…”

Abstract:This study presents an analysis of effectiveness of different designs of baffles, including the conventional, partial and oblique, in limiting the manoeuvre-induced transient as well as steady-state fluid slosh forces and moments in a partly-filled tank truck. The effect of an alternating arrangement of partial baffles is also explored. A three-dimensional computational fluid dynamics model of a partly-filled tank is developed to study the relative anti-slosh properties of different baffles designs and layouts under combined idealized longitudinal and lateral acceleration fields and different cargo loads. The analyses are also performed for a cleanbore tank, which is validated using the widely-used quasi-static slosh model. The results suggest that the conventional transverse baffles offer important resistance to fluid slosh under braking manoeuvres, while the obliquely placed baffles could help limit the longitudinal as well as lateral fluid slosh under combined lateral and longitudinal acceleration excitations.
