Fluid-structure interaction — A survey with emphasis on its application to nuclear steam system design

Assessment results of fluid-structure interaction numerical simulation using fuzzy logic

“…The equations of fluid dynamics and structural dynamics are coupled by the requirements that position and velocity of the points of structure and of fluid model, coinciding at the interface surface, are the same [10,14,18,19]. An iterative code coupling procedure, a timedomain partitioned solution approach [9] is used.…”

“…Fluid-structure interaction (FSI) has been the main focus of numerous studies motivated by applications in bridge construction [1], aeronautics [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], computer hardware design [17] or nuclear [18,19], but also in biomechanics and medicine [20][21][22]. Advances in computational mechanics algorithms parallel to continually growing computational resources allowed analysis of coupled fluid-structure problems using computer simulation.…”

“…Different methods for --------------modelling fluid-structure coupling have been extensively investigated [15,23]. Depending on physical problem assumptions, the models of one- [6,12,17,24] or two-way [5, 7-9, 11, 13, 14, 20, 25-27] load transfer, with various coupling mechanisms ranging from partitioned [7][8][9][10], weakly [8,18,22] coupled approach to strong [1,10,17] fully coupled, monolithic schemes, or both [17,22] coupling strategies were used in order to resolve problems of stability of plates in fluid flow and thin sheet fluttering [2,16,28] or fluid-thermal-structure coupled simulation of the response to simultaneous aerodynamic heating and fluctuating pressures [24,[25][26][27]. A limited number of studies have considered mutual two-way coupling of aerodynamic heating and structural deformation, while some studies have considered thermal effects by prescribing a steady-state temperature distribution, further simplifying problem by neglecting the transient thermal analysis in addition to two-way coupling [25,27].…”

“…The FSI is largely relied on numerical simulation of two different physical systems: Eulerian CFD perspective of the fluid model which could be based on different space discretization schemes as finite elements [1], finite difference [3,12,19] but frequently on finite volume method [3,5,8,16], and CSM supported by finite element method (FEM), and Lagrangian formulation of the solid [4,8,16,18,28]. Reliability of the obtained results depends on the adopted modelling assumptions and the level of approximation of the simulated physical process.…”
