A thorough understanding of the effects sloshing on aircraft dynamic loads is great relevance for future design flexible to be able reduce their structural mass and environmental impact. Indeed, high vertical accelerations caused by vibrations structure can lead fragmentation fuel free surface. Fluid impacts tank ceiling are potentially a new source damping that has hardly been considered befor...

Suspending a rectangular vessel partially filled with an inviscid fluid from a single rigid pivoting rod produces an interesting physical model for investigating the dynamic coupling between the fluid and vessel motion. The fluid motion is governed by the Euler equations relative to the moving frame of the vessel, and the vessel motion is given by a modified forced pendulum equation. The fully ...

A numerical study of damping effects on aircraft wings caused by liquid sloshing inside the fuel tanks has been performed. To model this phenomenon, a tank-fluid system is vertically excited with periodic law motion. The work two parts. In present Part I, mathematical formalism global energy balance in different frames reference provided. Then, an enhanced Smoothed Particle Hydrodynamics model,...

This paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. With regard the increasing importance of LNG carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

This paper presents a fluid sloshing model using the artificial neural network method (ANN). Determining in tank is challenging task due to its nonlinearity and complexity of behavior environmental operational conditions. Due problems laboratory modeling, use numerical modeling analyze this phenomenon can be justified. In paper, first, simulated by smooth particle hydrodynamics (SPH). The input...
