The analysis of liquid sloshing remains a challenging computational mechanics topic due to its complex underlying physics. rapid simulation problems requires accurate modelling two-phase fluid dynamics and impacts on solid tank boundaries by suitable Flexible Fluid Structure Interaction (FFSI) models. This paper presents hydroelastic model for the prediction sway induced loads flexible trapezoi...

This paper introduces the experimental results of sloshing model tests carried out at Seoul National University. Two 1/50-scale tanks, i.e., 2D and 3D models with the same shape, were manufactured for the comparative study. Particular interest was taken in the differences in impact pressures between the 2D and 3D models. Regular motion tests were conducted for different filling depths. For each...

We present several simulations carried out using Chrono::FSI and Chrono::Vehicle that highlight the two way coupling between the dynamics of a vehicle and the dynamics of a fluid that is free to move in a tank rigidly attached to the vehicle; i.e., a vehicle sloshing problem. The simulations are carried out in Chrono [1] using a monolithic solution; i.e., there is no co-simulation, the entire s...

Numerical and analytical results are presented for fluid sloshing, of a two-layer inviscid, incompressible and immiscible fluid with thin layers and a rigid lid, coupled to a vessel which is free to undergo horizontal motion governed by a nonlinear spring. Exact analytical results are obtained for the linear problem, giving the natural frequencies and the resonance structure, particularly betwe...

In the present paper we develop an approach to obtain sharp spectral asymptotics for Steklov type problems on planar domains with corners. Our main focus is two-dimensional sloshing problem, which a mixed Steklov—Neumann boundary value problem describing small vertical oscillations of ideal fluid in container or canal uniform cross-section. We prove two-term asymptotic formula eigenvalues. part...

It is difficult to evaluate the sloshing load acting on a fixed roof of tank because it depends on the collision of the liquid to the roof. In this paper, the SPH simulation was introduced to evaluate the load acting on a fixed roof. The results obtained by the simulation showed good agreement with those obtained from other method. In addition, the effect of the roof-liquid clearance on the slo...

Sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. In recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. On the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...
