“…The CFD method has been developed, which more accurately examines the response of the fluid to different excitations. [15][16][17] Yan et al 18 simulated twodimensional nonlinear sloshing in circular and conical tanks under ramp-step lateral acceleration using FLUENT CFD code. Fluid slosh parameters such as the coordinates of centre of gravity as well as vertical and horizontal forces are expressed as secondorder polynomial regression functions.…”

In this paper, a coupled model is developed to evaluate the effect of transient fluid slosh on the railway tank wagon dynamic vice versa. This model has computational complexity in solving the Navier–Stokes equations and nonlinear differential equations of tank wagon vibration with nonlinear wheel–rail contact. The coupled model can be used as an effective and robust tool compared to simplified models for assessing the stability of tank wagon. The transient fluid slosh model is analysed using the computational fluid dynamic method combined with the volume of fluid technique. The tank wagon dynamic model is solved using the fourth-order Runge–Kutta method based on the 19 degrees of freedom model with longitudinal, vertical, roll and pitch vibrations. The wheel–rail contact is considered according to nonlinear Hertzian and Kalker linear rolling contact theories. The fluid slosh model is validated using experimental data. The dynamic response characteristics of the partially filled railway tank wagon are investigated under straight-line braking manoeuvre using the coupled model. The results obtained from a parametric study, including the cross sectional shape and the filled volume show that the modified-oval cross section improves the dynamic response characteristics, which are attributed to its lower fluid's centre of gravity coordinate in the longitudinal direction and low lateral moment transfer of the fluid.

“…Such a general approach leads to a system of partial differential equations [7][8][9]. This system of equations is not solvable analytically, wherefore numerical solution techniques such as the finite difference method or the finite volume method have to be applied [10][11][12][13]. Models with distributed parameters can be used for motion optimization as shown in [14,15].…”

The present paper deals with the problem of modeling liquid slosh occurring in the packaging process of containers filled with liquid. Sloshing effects are induced by one-dimensional intermittent motions and are undesired due to the necessity of quality control processes, such as weighing. Therefore, motion optimizations are often applied with the intention to minimize the residual vibrations. Valid process models are required to do so. The aim of this paper is to derive models for describing the liquid slosh behavior for different motions and for common practical circumstances, e.g., different container geometries as well as machine operating speeds, and to state the model's limits of use. Known model approaches are discussed, and their assumptions are reviewed experimentally. This leads to a set of limited ranges of operating speeds in which the applied models' assumptions are valid. The models are derived for these sets from experimental data, and a comparison is executed that enables the determination of the models' validity concerning their operating speed dependency. Finally, the validity of the derived models is investigated by comparing their predictive efficiency of describing the vibration for different motion profiles.

“…In the literature, some researchers deal with determination of sloshing effect (Rawat et al 2019) and some determined the baffle effect on sloshing (Cheng, Jing, and Gong 2019;Sanapala et al 2018;Zheng et al 2018). In some researches, dam break problems were investigated (Demir et al 2019;Dinçer et al 2019; and in some others submerged elastic structures were investigated (Ghalandari et al 2019).…”
