An Arbitrary Lagrangian-Eulerian (ALE) formulation is applied in a fully coupled monolithic way, considering the fluid-structure interaction (FSI) problem as one continuum. The mathematical description and the numerical schemes are designed in such a way that general constitutive relations (which are realistic for biomechanics applications) for the fluid as well as for the structural part can b...

The use of flexible materials for primary mover and power takeoff wave energy converters (WECs) has attracted considerable attention in recent years, owing to their potential enhance the reliability, survivability, conversion efficiency. Although some reduced order models have been used study fluid–structure interaction (FSI) responses (fWECs), they are somehow inappropriate due limited accurac...

Wind effects on tensile fabric structures (TFS) are not extensively investigated. Available studies consider simplified TFS support conditions and comparisons between static dynamic analyses lacking. The response of a double hypar under varying wind speed is carried out by using fluid-structure interaction (FSI). Realistic considered. geometry determined through form-finding. Computational flui...

Occurrences such as the global climate change have presented critical challenges to humanity and necessitated studies into how greenhouse gas emissions can be minimized. One practical solution is generation of power from renewable sustainable sources; hence, tidal current energy which, however, also gives rise concept fluid-structure interaction (FSI). The pressure fluid flow aspects affect str...

In this paper, an offshore platform subjected to dynamic loading for different damage cases was modelled via fluid-structure interaction (FSI) analysis. Different models were considered in the case where one leg broken, and Young’s modulus of damaged member reduced with four severity ratios. addition five structures, undamaged structure according two spacing conditions. Thus, compared among the...

An experimental technique to accurately quantify the deformation and the bend-twist coupling of high performance composite foils under fluid loading is presented. The experimental results are reproduced in a Computational Fluid Dynamic (CFD) environment to assess the impact of board deflection and changes in pitch angle on vertical force generated in the C-foils while sailing under increased hy...

In this study the dynamic of a six petals reed valves pack is simulated accounting the complex fluid interaction phenomena occurring during transient flow of a typical working cycle of a two-stroke engines for go-kart competition. Starting from previous works on FSI (Fluid Structure Interaction) simulation for 2D cases and after the optimization of valve material considering only the structural...

The development of fluid-structure interaction (FSI) software involves trade-offs between ease of use, generality, performance, and cost. Typically there are large learning curves when using low-level software to model the interaction of an elastic structure immersed in a uniform density fluid. Many existing codes are not publicly available, and the commercial software that exists usually requi...

This paper describes a strategy to solve multifluid and Fluid Structure Interaction (FSI) problems using Lagrangian particles combined with a fixed Finite Element (FE) mesh . The method is an extension from the fluid-only PFEM-2 [14][15], which uses explicit integration over the streamlines to improve accuracy. As a result, the convective term does not appear in the set of equations solved in t...

The authors present a thermally and dynamically coupled fluid–structure-interaction (FSI) model of thermoforming process variant along with simulation results. By purposeful arrangement the inlet nozzles, under consideration seeks to improve deformation behavior plastic sheet made polyvinyl chloride (PVC), ultimately leading more uniform wall thickness distribution. In order capture complex int...
