Damping induced by vertically sloshing liquids at large amplitudes is of interest in the understanding dynamic response aircraft wings containing fuel. This work presents experimental investigation sloshing-induced damping two small rectangular tanks ( L = 100 mm , h 37 . 5 and 50 ) under vertical excitation various frequencies (3.3 to 10 3 Hz (up 1.57 tank heights). The focus placed on that le...

In the present work damping effect of sloshing flows in tanks subjected to vertical harmonic oscillations is modelled through Smoothed Particle Hydrodynamics (SPH) numerical method. The prediction energy dissipation these problems interest, among others, aeronautic field appropriately address sloshing-induced loads on aircraft wings. To this purpose, an enhanced SPH scheme applied and extensive...

Abstract Challenges for steady and unsteady model motion in a large water towing tank procedures to overcome them are the focus of presented work. Some challenges attributed experiments conducted water, whereas others uniquely ascribed facility. Data convergence outlier detection studied based on phase averaged pressure order ensure proper data quality. Pressure measurements performed with non-...

A semi-analytic study on two-layered liquid sloshing in a horizontal excited two-dimensional rectangular tank with elastic baffle was performed. The present work is further development of the semi-analytical technique for solving single-layer problem. located lower or upper liquid. First, complex domain baffled divided into several simple sub-domains to solve analytic solution. wet mode present...
