This study conducts experimental research on the liquid sloshing performance of a vane-type tank used in high orbit satellites. The tests without propellant management device (PMD) were developed under different liquid-filling ratios. Liquid with PMD performed directions and test results agree considerably theoretical results, indicating system’s reliability. A linear relationship was observed ...

Vibration of a floating roof in cases tube and foam seals has been analyzed by ANSYS. Fluid-Structure Interaction (FSI) sloshing phenomenon have considered. Modal responses, time waves frequency spectrums the vibrations two sealing were evaluated during horizontal seismic excitation tank base. Then, effects main mechanical factors seal on vibration investigated. The amplitude case was considera...

Due to the significant health and economic impact of blood vessel diseases on modern society, its analysis is becoming of increasing importance for the medical sciences. The complexity of the vascular system, its dynamics and material characteristics all make it an ideal candidate for analysis through fluid-structure interaction (FSI) simulations. FSI is a relatively new approach in numerical a...

We propose a numerical scheme to compute the motion of a two-dimensional rigid body in a viscous fluid. Our method combines the method of characteristics with a finite element approximation to solve an ALE formulation of the problem. We derive error estimates implying the convergence of the scheme. 1991 Mathematics Subject Classification. 35Q30, 65M12, 76D05, 76M10.

This paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (MIMO) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. The agents may have different dynamics and communicate together under a directed graph. A distributed adaptive method is designed for both cases. The structures of the contro...

We present our recent work on interface reconstruction in a logically structured Lagrangian CFD code that now incorporates the MoF system developed by Shashkov’s group at LANS. We also discuss the models used to update and re-map the state variables in the mixed
