“…Considering that the change in the quantities of interest for this benchmark slows down after 55 s of flow for Re = 100, we did not report the results for EFR with mesh 700k as they are not close enough to steady state. We would like to mention that in [29] the authors report over 200 computation hours with solids4Foam to simulate 2.32 seconds of a FSI problem at Re ∼ 2000 with a Smagorinski-based LES model. They used 20 Intel Xeon CPUs E7-8870 @ 2.40 GHz processor cores.…”

“…To the best of our knowledge, it is the first time that the Leray model is used within a FSI context, although obviously other LES approaches have been used. In particular, see [29,30] for numerical results obtained with LES techniques implemented in foam-extend and applied to FSI problems. The big advantage of the EFR method is modularity: its implementation does not require any major modification of a legacy solver.…”

“…We compare our results with those obtained in [32], where the authors use a finite difference based immersed-boundary method for the fluid problem and a finite element formulation for the structure problem. This benchmark has also been studied in laminar regime in [33], as well as at higher Reynolds numbers (of the order of a thousand) in [26,29,34].…”

The goal of this paper is to test solids4Foam, the fluid-structure interaction (FSI) toolbox developed for foam-extend (a branch of OpenFOAM), and assess its flexibility in handling more complex flows. For this purpose, we consider the interaction of an incompressible fluid described by a Leray model with a hyperelastic structure modeled as a Saint Venant-Kirchho material. We focus on a strongly coupled, partitioned fluid-structure interaction (FSI) solver in a finite volume environment, combined with an arbitrary Lagrangian-Eulerian approach to deal with the motion of the fluid domain. For the implementation of the Leray model, which features a nonlinear differential low-pass filter, we adopt a three-step algorithm called Evolve-Filter-Relax. We validate our approach against numerical data available in the literature for the 3D cross flow past a cantilever beam at Reynolds number 100 and 400.

“…The FSI loop may involve many iterations until convergence in Figure 1. The fluid displacement at the ( i + 1)‐th iteration step is given as [ 22 ]

{bold-italicd}_{f, i + 1} = ω_{i} {bold-italicd}_{s, i + 1} + (1 - ω_{i}) {bold-italicd}_{f, i}

where

ω_{i}

is the relaxation factor,

{bold-italicd}_{f, i}

is the fluid displacement at the i th iteration step, and

{bold-italicd}_{s, i + 1}

is the solid displacement at the

(i + 1)

Analysis is performed for fluid–structure interaction (FSI) by nozzle clogging in the continuous steel casting process. The scope of the analysis is confined to a submerged entry nozzle (SEN) interacting with turbulent molten steel flow. The fluid and solid domains are discretized in a single framework of the finite volume method in the OpenFOAM‐Extend version. Flow displacement by the clog is tracked and modal analysis performed to predict the vibration frequencies due to clogging. Parametric study is performed with respect to casting speed and immersed depth in the mold without clogging and with respect to the clog mass and its distribution on inner wall, bottom wall, and exit in the SEN. Results show the dominant frequency primarily influenced by the total mass of clog and not much affected by the clogging locations with good agreement between measurement and simulation.

“…One gap of the current OpenFOAM FSI approach is that it has only been applied to single-phase fluid modelling (Rege and Hjertager, 2017). Therefore, it has not been applied to ocean engineering applications containing both air and water.…”

Fluid-structure interaction of a large ice sheet in waves

With global warming, the ice-covered areas in the Arctic are being transformed into open water. This provides increased impetus for extensive maritime activities and attracts research interests in sea ice modelling. In the polar region, ice sheets can be several kilometres long and subjected to the effects of ocean waves. As its thickness to length ratio is very small, the wave response of such a large ice sheet, known as its hydroelastic response, is dominated by an elastic deformation rather than rigid body motions. In the past 25 years, sea ice hydroelasticity has been widely studied by theoretical models; however, recent experiments indicate that the ideal assumptions used for these theoretical models can cause considerable inaccuracies. This work proposes a numerical approach based on OpenFOAM to simulate the hydroelastic wave-ice interaction, with the Navier-Stokes equations describing the fluid domain, the St. Venant Kirchhoff solid model governing the ice deformation and a coupling scheme to achieve the fluid-structure interaction. Following validation against experiments, the proposed model has been shown capable of capturing phenomena that have not been included in current theoretical models. In particular, the developed model shows the capability to predict overwash, which is a ubiquitous polar phenomenon reported to be a key gap. The present model has the potential to be used to study wave-ice behaviours and the coupled wave-ice effect on marine structures.
