The coupled normal flux and fixed dummy particle boundary treatment method was chosen to impose the boundary conditions, and an enhanced Riemann SPH solver was introduced to smooth transitions of field variables near the interface. Robustness and accuracy of the proposed method were validated through three typical FSI cases, including water entry of the 2D cylinder, sinking of an eccentric rigid box and water entry of a wedge.

Second, results from a newly developed analytical model reveal that the flap’s oscillation frequency depends on the local flow velocity ahead of it and varies significantly as a function of the flap location. Trailing-edge flaps that experience low local velocities oscillate at their structural natural frequency. Meanwhile, leading-edge flaps with higher local velocity oscillate at a higher frequency than their natural frequency due to the aerodynamically induced added stiffness. The flap dynamics also depend on the energy spectrum of the flow, where flaps with lower effective oscillation frequencies exhibit higher fluctuations because they coincide with the flow’s high-energy frequency band. Finally, varying the flap’s inertia and hinge stiffness tunes its mean position and fluctuations to enhance the flow control mechanism employed by the flap. For instance, trailing-edge flaps enhance lift by acting as a pressure dam, with maximum effectiveness when the flap is perpendicular to the airfoil’s surface. Leading-edge flaps, on the other hand, improve lift by reducing adverse geometric pressure gradients, with maximum aerodynamic benefits occurring when the flap interacts with the shear layer with minimal fluctuations.

During the service lifespan, SFTs have the risk of wave impact. Therefore, to ensure safety and stability of the SFTs, hydrodynamic tests of a 1:60 scaled model were carried out in a large pool with underwater vibration table, where data on acceleration, roll, pitch rotation, yaw rotation, displacement, variation table and cable tension were collected. Comprehensive investigation was conducted to explore the excitation effects and hydroelastic responses of the model under regular and earthquake-induced waves with different immersion depths along with the modal characteristic analysis. The results show that the natural frequency of the SFT is significantly influenced by the angle of the cables. As the angle increases, the vertical stiffness of the system also increases, which consequently raises the natural frequency of the structure. According to hydrodynamic analysis, shallower the depth of the SFT, the more it hinders the propagation of waves, resulting in subsequent wave attenuation but aggravating structural responses. Furthermore, under regular and earthquake-induced waves, harmonic resonance can be triggered. The acceleration, roll angle, and cable tension undergo the most significant changes at the mid-span section. The increase in cable tension on the upstream side exceeds the decrease in tension under higher frequency wave due to wave impact force. There are discrepancies in angle responses among the cross-sections and the mid-span section demonstrates larger roll angles and smaller pitch and yaw angles, leading to phase angle deviations among the three variations. For earthquake-induced waves, more pronounced structural responses result from greater seismic acceleration amplitude and shallower immersion depth. And the response relationship between sway and heave, as well as the periodic variations in mooring cable tension and angle, remains consistent with that under regular waves. This consistency underscores that the dynamic behavior of the SFT is primarily governed by the intrinsic structural properties and hydrodynamic interactions, rather than the specific nature of the wave excitation.</div></div>","PeriodicalId":54834,"journal":{"name":"Journal of Fluids and Structures","volume":"135 ","pages":"Article 104317"},"PeriodicalIF":3.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This rectangular cylinder has two VIV lock-in regions. According to the surface pressure distribution characteristics, it is deduced from the proposed simplified vortex theory that there are significant vortices drifting on the upper and lower surfaces of the rectangular cylinder, and the vortex experiences approximate two and one vibration period drifting from the leading edge to the trailing edge in the first and second lock-in region, respectively.

The front three non-zero DMD mode frequencies are about 1–3 times of the natural frequency of the rectangular cylinder, respectively. Multiple vortices are also observed on the upper and lower surfaces in the high-order DMD modes, especially in the second lock-in region, indicating the importance of vortex drifting phenomenon in the occurrence of VIV.

For the structure model, a second-order discretization of the deformation gradient tensor (F2nd) is implemented to improve the accuracy of stress and strain computation. To mitigate numerical noises in the reproduced stress fields and improve numerical stability, a Riemann Stabilization (RS) term is incorporated in the structural momentum equation. A Dynamic Hourglass Control (DHGC) scheme being parameter-free is proposed to mitigate the spurious zero-energy modes linked with rank deficiency as a challenging issue for collocated computational methods including the total Lagrangian SPH. The novelty of this scheme is that it dynamically adjusts the hourglass control coefficient based on the instantaneous state of particle distributions and time evolution of an error function. For the fluid model, the Velocity divergence Error Mitigating (VEM) scheme and Hyperbolic/Parabolic Divergence Cleaning (HPDC) scheme are adopted to suppress spurious fluid pressure noises and hence enhance the modelling of fluid-structure interactions. Validations in terms of robustness and accuracy of the proposed model are carried out via five structure examples and three FSI ones. The results demonstrate that more physically consistent stress and strain fields are reproduced by the implementation of F2nd and RS. The proposed DHGC scheme effectively suppresses hourglass modes and is case- and resolution-independent (in contrast to the traditional Hourglass Control scheme).
