The large-amplitude sloshing behavior of liquid hydrogen in a tank for heavy-duty trucks may have adverse effects on the safety and stability driving. With successful application field new energy vehicles, coupled thermodynamic performance during becomes more attractive. In this paper, three-dimensional numerical model is established to simulate coupling characteristics horizontal trucks. calcu...

This study investigates natural frequency analysis of an FG composite rectangular plate partially contacting with a bounded fluid. The material properties are assumed to be varying continuously through the thickness direction according to a simple power law distribution in terms of volume fraction of material constituents. Wet dynamic transverse displacements of the plate are approximated by a ...

This work is devoted to the numerical analysis of vertical elastic coaxial cylindrical shells completely or partially filled with a quiescent compressible fluid account for sloshing its free surface. The problem solved in axisymmetric formulation using semi-analytical version finite element method. medium described by wave equation, which together conditions prescribed at boundaries reduced wea...

dynamic behavior of ground supported cylindrical storage tanks (cst) is of crucial importance because of its applications in industrial complexes. seismic behavior of tanks is greatly affected by the height to diameter ratio, fluid height and fluid type. five csts with different height to diameter ratios, three csts with the same height and diameters but various fluid heights and one cst with t...

The liquid cargo contained in a partly-filled road tank vehicle is prone to dynamic slosh movement when subjected to external disturbances. The slosh behavior has been identified as a significant factor impairing the safety of liquid cargo transportation. The laboratory experiments have been conducted for analyzing fluid slosh in partly filled tanks. The experiment results measured under forced...

Non-linear free-surface phenomena, such as extreme waves and violent sloshing, and their impact on the dynamics response of the containing vessels have long been subjects that could only be studied with experimental methods. Nowadays, computational CFD tools can make a significant contribution to these flow problems. The paper starts with a short overview of the most popular numerical methods t...

Speedmeters are known to be quantum non-demolition devices and, by potentially providing sensitivity beyond the standard quantum limit, become interesting for third generation gravitational wave detectors. Here we introduce a new configuration, the sloshing-Sagnac interferometer, and compare it to the more established ring-Sagnac interferometer. The sloshing-Sagnac interferometer is designed to...

Low-capillary number or surface tension dominated flows are found in a number applications, ranging from small scale microfluidics up to larger scale analysis of microgravity sloshing. This paper evaluates the possibility of modelling of surface tension dominated multiphase flows using an Eulerian volume-of-fluid (VOF) approach with high-resolution surface capturing. With the aim of improved st...

This paper proposes Reduced-Order Models (ROMs) based on data provided by Computational Fluid Dynamics (CFD) simulations for generally flexible tanks to be embedded in a larger aerospace structure. A commercial off-the-shelf CFD code addressed sloshing analyses is employed generate set used the synthesis of system ROM. The developed ROM, Linearized Frequency Domain (LFD) approach, makes use an ...
