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...

Vertical sloshing of liquid-filled tanks has been shown to induce substantial dissipative effects. Building upon these previous results obtained on simpler systems, a scaled wing prototype is presented here, equipped with fuel tank that allows the observation liquid and quantification induced dynamic Based experiments conducted at 50% filling level for baffled model, additional damping effects ...

In this investigation, a pneumatic suspension model with orifice damping is developed and used to evaluate the performance of air in comparison coil-spring railroad highway transportation systems. railcars, springs are isolate car from vibrations caused by track irregularities, while trucks, often their rear suspensions allow adjusting characteristics depending on load conditions. The spring fo...

A machine learning technique is proposed to derive the damping rate functions in co-called single-dominant modal system describing resonant liquid sloshing a rectangular tank performing harmonic longitudinal motions. Its implementation demonstrated for steady-state (periodic) resonance waves when admits an analytical asymptotic solution depending on introduced functions. Recent experiments by B...

Clearance of Thrust Vector Control (TVC) laws for launchers demands the capability to provide analytical certificates for the system’s robust stability. During exo-atmospheric flight, a key role is played by the ability to deal with non rigid-body effects such as fuel sloshing. Depending on its frequency and magnitude, sloshing can easily deteriorate the performance of the TVC laws to the point...

This is the first in a series of two papers aiming to establish sharp spectral asymptotics for Steklov type problems on planar domains with corners. In the present paper we focus on the two-dimensional sloshing problem, which is a mixed Steklov-Neumann boundary value problem describing small vertical oscillations of an ideal fluid in a container or in a canal with a uniform cross-section. We pr...
