an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

This paper presents general stability conditions for a spinning spacecraft with partially liquid-filled tanks by using Rumyanstev and Mclntyre methods. These methods are compared for accuracy and limitation by applying them to a specific case of a spinning spacecraft with two partially liquid-filled tanks. The stability conditions require that, for a stable motion, the spin to transverse moment...

Sloshing interaction in ship collisions is studied both experimentally and numerically. The rapid change in ship motions resulting from contact loading in collisions initiates violent sloshing inside partially filled liquid tanks on board. Sloshing affects the collision dynamics and reduces the amount of energy available for structural deformations. An understanding of this interaction phenomen...

A dynamical system involving the decaying test of a partially filled liquid tank is analyzed in present paper. This analysis relevant for design aircraft fuel tanks, where wings' ...

The disturbance on the free surface of the liquid when the liquid-filled tanks are excited is called sloshing. This paper examines the nonlinear sloshing response of the liquid free surface in partially filled two-dimensional rectangular tanks using finite element method. The liquid is assumed to be inviscid, irrotational, and incompressible; fully nonlinear potential wave theory is considered ...

Conventional liquefied natural gas (LNG) cargo vessels are imposed with tank-fill limitations as precautions to prevent structural damage and stability-loss due high-impact sloshing, enforcing volume-fills be lower than 10% or higher 70% of the tank height. The restrictions, however, limit commercial operations, specifically when handling spot trades offshore loading/unloading at multiple ports...
