“…Finally, building on an existing design developed by UKRI-STFC, an alternative open-source framework has been developed in parallel with the commercial solution (Ref. [32]), this is also based on MUI but utilises freely available structural and fluid solvers. Fundamentally, it provides a similar coupled solution to the main commercial option, offering a validated and easily developed test framework for the consortium to collaborate around where not all have direct access to source code in the case of the commercial solvers.…”

The SLOshing Wing Dynamics (SLOWD) project aims to investigate the modelling of fuel sloshing physics to reduce the design loads on aircraft structures. This goal will be achieved through investigating the damping effect of sloshing on the dynamics of flexible wing-like structures carrying liquid (fuel) via the development of experimental set-ups complemented by novel numerical and analytical tools. The primary focus of the project is the application of modelling capabilities to the wing design of large civil passenger aircraft (subject to EASA CS-25 type certification), which are designed to withstand the loads occurring from atmospheric gusts, turbulence and landing impacts. The timeframe of the project is three years, starting in September 2019. This paper reviews the current progress that has been made and outlines goals for the rest of the project.

“…In our work herein, the extent of the interface compression is set conservatively, such that spurious deformation is prevented, while still being effective in reducing interface numerical diffusion. The OpenFOAM keyword cAlpha controls the extent of this compression and is set to the widely adopted value of 1 in all simulations presented [37].…”

“…Finitevolume discretisation combined with the Volume of Fluid (VoF) method is available in many commercial and open-source CFD solvers and presents a common methodological approach to solving sloshing-type problems. Higuera et al [31], Ransley [32] and Hu et al [18] used VoF to study waves and their interactions with fixed and floating structures, with a good agreement with experimental data, and the successful use of VoF for sloshing problems was demonstrated in [33][34][35][36][37][38][39][40].…”

As part of a wider project to understand the applicability of utilising slosh-based damping for wing-like structures, simulations of partially filled tanks subjected to harmonically oscillating and vertical motion are presented. The Volume of Fluid modelling approach is used to capture the air–water interface and different turbulence models based on the Reynolds Averaged Navier–Stokes equations employed. No-model simulations are also conducted to demonstrate the efficacy of using turbulence models in the simulation of sloshing flows. Accuracy of the models is assessed by comparing with recent well-validated experimental data in terms of the damping effect of the sloshing. A wide range of excitation amplitudes are considered in the study to demonstrate the effectiveness of different turbulence models in representing the flow feature of weak and very violent sloshing. The results show that standard turbulence models can produce an excessive dissipation, especially at the interface, leading to inaccuracies in the estimation of sloshing dynamics of the violent sloshing. This issue is absent in the no-model simulations, and better results are obtained for all tested sloshing conditions, suggesting approaches to mitigate this interfacial dissipation within RANS-based modelling is an important consideration for future direction.

OpenFOAM-preCICE: Coupling OpenFOAM with External Solvers for Multi-Physics Simulations

2023

View full text Add to dashboard Cite

Multi-physics simulations, such as conjugate heat transfer or fluid-structure interaction, are often constructed completely in OpenFOAM. However, they can also be formed by coupling OpenFOAM to third-party simulation software via a coupling tool. This approach indirectly adds to the capabilities of OpenFOAM those of other simulation tools (such as physical models or discretization methods more fitting for specific applications), and allows building complex multi-physics simulations by connecting specialized single-physics codes. We present the OpenFOAM-preCICE adapter, a function object that enables standard OpenFOAM solvers to use the open-source, massively parallel coupling library preCICE, without requiring any code modifications. We review alternative coupling approaches, analyze our design decisions, peek into key implementation details, validate the adapter, study the effect on runtime, and give an overview of the growing community of users and contributors.
