“…The computed fluid force profile has the same general profile that the total fluid force calculated by STABLE and REN in the case of a three dimensionnal square geometry, with an incompressible, viscous and turbulent fluid, in their study of the dynamic analysis of fuel storage racks subjected to seismic loads [19]. A complementary numerical study is performed to show the convergence of the calculations as the mesh is refined, for the case of large motion of the inner cylinder, Fig.…”

This paper is related to the study of a nuclear propulsion reactor prototype for the French Navy. This prototype is built on ground and is to be dimensioned toward seismic loading. The dynamic analysis takes the coupled fluid structure analysis into account. The basic fluid models used by design engineers are inviscid incompressible or compressible. The fluid can be described in a bidimensional by slice or a three-dimensional approach. A numerical study is carried out on a generic problem for the linear FSI dynamic problem. The results of this study are presented and discussed. As a conclusion, the three-dimensional inviscid incompressible fluid appears to be the best compromise between the description of physical phenomena and the cost of modeling. The geometry of the reactor is such that large displacements of the structure in the fluid can occur. Therefore, the linearity hypothesis might not be longer valid. The case of large amplitude imposed oscillating motion of a cylinder in a confined fluid is numerically studied. A CFD code is used to investigate the fluid behavior solving the NAVIER-STOKES equations. The forces induced on the cylinder by the fluid are computed and compared to the linear solution. The limit of the linear model can then be exhibited.

For needs of transportation, it is more and more obvious of the bridge unsafe, and the study of bridge safety monitor will become more important at the area of civil engineering. In this paper we discuss the methods of digital ground photogrammetry for bridge safety monitoring and the application of those, we took digital cameras and 3-D laser scanners as the tools for close-range photogrammetry, and adopted 3D Time Baseline Parallax combined with Kalman Variance Filters as the theories for monitoring dynamic deformation, then developed software to deal with data, which can draw curves of dynamic deformation automatically, we can monitor the deformation regularity by these curves effectively, then we can monitor and analysis the safety of bridges by this way. The method we designed is very simple and economical, and we also did a lot of experiments to verify availability of this system, and we happy to say that the system has the characteristics of high automation degree, large data collection capacity and strong system reliability, etc. It will be practical value at the area of civil engineering.

“…Even though diverse criteria exist in dividing the FSI problems, FSI problems can be classified into two categories according to the continuity of the solid: (i) FSI problems between the fluid and the continuous solids (FSI‐C) and (ii) FSI problems between the fluid and the discontinuous solids (FSI‐D) . The simulation methods are relatively mature for FSI‐C problems with small motion of the solids . Problems with large movement of the solids, though challenging, can be solved by various approaches, including the arbitrary Lagrangian‐Eulerian (ALE) method, the overset mesh method, the fictitious domain method, and so on.…”

Summary A novel resolved combination of the computational fluid dynamics and the discrete element method (CFDEM) is proposed for the simulation of the strong coupling between the fluid and the discontinuous solids with large movement. The fluid flow governed by the full Navier‐Stokes equations is simulated using fixed grids based on the Eulerian framework, whereas the motion of the discontinuous solids is modeled by the discrete element method using the Lagrangian description. The key challenge, namely, the representation of the moving interfaces between the fluid and the solids in different frameworks, is handled by the immersed boundary method. Meanwhile, the governing equations of the coupled system are solved by the partitioned method in an iterative way to achieve a strong coupling effect. The breakthrough of the proposed resolved CFDEM method lies in the calculation of the fluid flow in fixed grids with high resolution, along with an accurate simulation of the interaction between the fluid and the discontinuous solids with arbitrary shapes and large movement. The reliability and the accuracy of the new method are validated by calculating several well‐known benchmark examples. Good agreements are achieved between the present and the known results.
