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...

We consider the problem of active reduction of the structural vibrations induced by the sloshing of large masses of fuel inside a partly full tank. The proposed study focuses on an experimental device mimicking an aircraft wing made of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid. After deri...

The tank is one of the most important components in train which serves as a place to store fuel. However, so far has been component that gone unnoticed, even though there very issue consider, namely how fluid moves due movement while moving. free liquid called sloshing. Sloshing can be reduced by adding anti-sloshing baffles. So it necessary simulate sloshing taking into account value vehicle s...

The directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. The dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank mode...

Parallel analyses about the dynamic responses of a large-scale water conveyance tunnel under seismic excitation are presented in this paper. A full three-dimensional numerical model considering the water-tunnel-soil coupling is established and adopted to investigate the tunnel’s dynamic responses. The movement and sloshing of the internal water are simulated using the multi-material Arbitrary L...

The effort to reduce costs and environmental impact of modern commercial aircraft requires an ever better understanding physics, including the characterisation effective damping introduced on a structure by slosh dynamics. In this paper experimental vertical sloshing dissipative behaviour rectangular tank, representative scaled wing is addressed. Specifically, controlled electrodynamic shaker e...

We present a new cell-centered multi-material Arbitrary Lagrangian Eulerian (ALE) scheme to solve the compressible gaz dynamics equations on two-dimensional unstructured grid. Our ALE method is of the explicit time-marching Lagrange plus remap type. Namely, it involves the following three phases: a Lagrangian phase wherein the flow is advanced using a cell-centered scheme; a rezone phase in whi...

elevated tanks are very important structures and consist of various types. water supply is vital to control fires during earthquakes. also they are utilized to store different products, like petroleum supplies in cities and industrial zones. damage to these structures during strong ground motions may lead to fire or other hazardous events. elevated tanks should stay functional after and before ...
