“…Structural modelling of diffuser is performed by ABAQUS/Explicit and internal-external flow modelling is created ABAQUS/CFD simultaneously. While the structural verification of FEM is determined by SDOF model [19,20], CFD results are confirmed by computing energy and continuity equations given by Eqns. (15,16) [7].…”

In the scope of this study, main pipe of the diffuser, risers, ports, internal and external environments forming the discharge system which is used in application are modelled by Finite Elements Analysis (FEA) program to obtain discharge and structural behaviour. The last two spans of the system (20 m) and four ports on these spans are investigated. While the diameter and geometry of the risers and ports remain constant, the diffuser pipe is modelled in three different ways. These are constant sectioned (Model 1), contracting with sharp edge entrance sectioned (Model 2) and gradually contracting sectioned (Model 3) respectively. Among them, only Model 1 is treated as Single Degree of Freedom (SDOF) system and it is simulated by FEA to verify FEA solver in the first place. After structural suitability is confirmed, rest of the models are analysed to determine reaction forces and stresses. The discharge is performed as unsteady external flow as well as steady external flow assumption which is widely used in external flow model in the literature. The discharge analyses are performed in two different ways to verify FEA program. Iterative method is accompanying to FEA program. As a result of this study, proper model for structural and discharge behaviour and external flow effects on discharge velocities are obtained.

“…On the other hand, inflatable structure is defined when the numerical grids move and deform with the material in the traditional Lagrangian description of motion in the Lagrange method [18,21]. According to relevant literature, analytical [22], numerical [23] and experimental methods [24] have been used to model dynamic behaviour of the pile-supported offshore structures. In this study, the dynamic behaviour of structures under the effect of wind and wave forces is investigated by semi-analytical and numerical methods.…”

Marine structures are nowadays used in a variety of ways. The analysis of a tripod-type offshore structure sixty m in total height is performed in this study. In addition to operation-related loads, the structure is also under the effect of wind and wave loads. While the Eurocode velocity profile is used to calculate wind forces, the Airy wave velocity profile is utilized to determine wave forces. The model is created by a finite elements analysis program, and is composed of fluid and structural parts. The interaction of the parts is ensured by Coupled Eulerian Lagrangian (CEL) technique.

“…The second best performance was registered for the multi-pile type model. The bidirectional fluid structure interaction is ignored in these studies [10][11][12][13]. While both the structure and the fluid are modelled in bidirectional interaction, only the structure is modelled and flow forces are transferred to the model in unidirectional interaction.…”

Wave theory effects on behaviour of a 3D truss offshore structure Dynamic analysis of a four legged offshore truss structure under the effect of wave forces is conducted in this study. The structure is a three-storey space frame system formed of cylindrical members whose legs are supported by lateral bracings and vertical diagonals. The structure and its environment are numerically modelled by the finite elements method with the fluid-structure interaction. Due to climatic reasons, various wave theories may be applied to the structure. Therefore, the offshore environment is modelled in numerical analysis by the Linear, Stokes 2, and Stokes 5 wave theories, separately. Utjecaji teorije valova na ponašanje izvanobalne prostorne rešetkaste konstrukcije U radu je provedena dinamička analiza izvanobalne rešetkaste konstrukcije s četiri pojasa pod utjecajem sila valova. Konstrukcija je prostorni rešetkasti sustav s tri etaže formirana od cilindričnih elemenata, a čiji su pojasi osigurani uzdužnim spregovima s vertikalnim dijagonalama. Konstrukcija i njezin okoliš su numerički modelirani metodom konačnih elemenata uz interakciju fluida i konstrukcije. Zbog klimatskih razloga, konstrukcija može biti izložena različitim teorijama valova, pa je izvanobalni okoliš modeliran pomoću zasebnih teorija valova i to linearne, Stokes 2 i Stokes 5 teorije.
