Book Synopsis Three-dimensional Finite Element Formulation for Fluid-structure Interaction by :
Download or read book Three-dimensional Finite Element Formulation for Fluid-structure Interaction written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The safety evaluation of fast reactors often involves the modeling of various types of structural components which interact with surrounding fluid in three-dimensional space. In this paper, several key areas for performing three-dimensional fluid-structure interaction calculations are discussed. A new development is presented for a three-dimensional hexahedral hydrodynamic finite-element based upon a Quasi-Eulerian approach. By using trilinear shape functions and assuming a constant pressure field within the element, simple relations are obtained for internal nodal forces. The forms developed are easily coded and computationally efficient. Because the formulation is based upon a rate approach it is applicable to problems involving large displacements. Only adiabatic processes are considered. The difficult tasks (1) of input data preparation and checking and (2) the displaying of computed results are discussed. The use of automatic mesh generators, input data error analysis, and graphical display of the finite element meshes used to model reactor components are shown to ease the input task. In the final section, the formulation is applied to the three-dimensional fluid-structure interactions involved in a current reactor safety problem.

Book Synopsis Finite Element Solution of Interface and Free Surface Three-dimensional Fluid Flow Problems Using Flow-condition-based Interpolation by :
Download or read book Finite Element Solution of Interface and Free Surface Three-dimensional Fluid Flow Problems Using Flow-condition-based Interpolation written by and published by . This book was released on 2015 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The necessity for a highly accurate simulation scheme of free surface flows is emphasized in various industrial and scientific applications. To obtain an accurate response prediction, mass conservation must be satisfied. Due to a continuously moving fluid domain, however, it is a challenge to maintain the volume of the fluid while calculating the dynamic responses of free surfaces, especially when seeking solutions for long time durations. This thesis describes how the difficulty can be overcome by proper employment of an Arbitrary Lagrangian Eulerian (ALE) method derived from the Reynolds transport theorem to compute unsteady Newtonian flows including fluid interfaces and free surfaces. The proposed method conserves mass very accurately and obtains stable and accurate results with very large solution steps and even coarse meshes. The continuum mechanics equations are formulated, and the Navier-Stokes equations are solved using a 'flow-condition-based interpolation' (FCBI) scheme. The FCBI method uses exponential interpolations derived from the analytical solution of the 1-dimensional advection-diffusion equation. The thesis revisits the 2-dimensional FCBI method with special focus on the application to flow problems in highly nonlinear moving domains with interfaces and free surfaces, and develops an effective 3-D FCBI tetrahedral element for such applications. The newly developed 3-D FCBI solution scheme can solve flow problems of a wide range since it can handle highly nonlinear and unsteady flow conditions, even when large mesh distortions occur. Various example solutions are given to show the effectiveness of the developed solution schemes.
Book Synopsis Finite Element Formulation for Fluid-structure Interaction in Three-dimensional Space by :
Download or read book Finite Element Formulation for Fluid-structure Interaction in Three-dimensional Space written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A development is presented for a three-dimension hexahedral hydrodynamic finite-element. Using trilinear shape functions and assuming a constant pressure field in each element, simple relations were obtained for internal nodal forces. Because the formulation was based upon a rate approach it was applicable to problems involving large displacements. This element was incorporated into an existing plate-shell finite element code. Diagonal mass matrices were used and the resulting discrete equations of motion were solved using explicit temporal integrator. Results for several problems were presented which compare numerical predictions to closed form analytical solutions. In addition, the fluid-structure interaction problem of a fluid-filled, cylindrical vessel containing internal cylinders was studied. The internal cylinders were cantilever supported from the top cover of the vessel and were periodically located circumferentially at a fixed radius. A pressurized cylindrical cavity located at the bottom of the vessel at its centerline provided the loading.

Book Synopsis 3D Multi-scale Finite Element Analysis of the Present-day Crustal State of Stress and the Recent Kinematic Behaviour of the Northern and Central Upper Rhine Graben by : Thies Buchmann
Download or read book 3D Multi-scale Finite Element Analysis of the Present-day Crustal State of Stress and the Recent Kinematic Behaviour of the Northern and Central Upper Rhine Graben written by Thies Buchmann and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the contemporary stress state of a continental rift structure, the Upper Rhine Graben, and its present-day reactivation and kinematic behaviour. The graben is currently characterised by relatively slow tectonic deformation accompanied by low to medium seismicity and ongoing subsidence. In this context, the reactivation potential of pre-existing faults associated with the graben structure is one of the main goals of this thesis. Three dimensional finite element modelling is used for simulating the stress state of the study area. Based on the evaluation of the fault reactivation potential, a possible contribution of mechanical earth modelling to earthquake hazard assessment is also investigated. Another task of this thesis is the development of a method and work process for the construction of complex model geometries based on the different data types available. In order to establish a procedure that is independent of local computing and software facilities, the work-flow used is predominantly based on commercial software packages. A brief introduction is given on crustal stresses, their definition, determination and classification. Two approaches of shear failure reactivation evaluation, independent of the rheological parameter of fault surfaces, are discussed. In addition, a summary of the finite element method is given. This includes the influence of mesh quality and the implementation of contact problems as well as the ABAQUS implementation of the material models used (elasticity and elasto-plasticity). The thesis also refers to the approach of multi-scale modelling, nesting or sub-modelling using ABAQUS. The consequences of this approach on the boundary conditions and the model geometries are discussed.
Book Synopsis Finite Element Simulation of Simple Three-dimensional Fully Cavitating Flows by : Peter Y. Ko
Download or read book Finite Element Simulation of Simple Three-dimensional Fully Cavitating Flows written by Peter Y. Ko and published by . This book was released on 1979 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on potential flow theory, a formulation is given for three-dimensional fully cavitating flow with a Riabouchinsky model. The model is nonlinear and the location of the free surface of the cavity is not known priori. Therefore, an iterative procedure is used to locate the free surface boundary. The employment of a trial-free-boundary approach effectively reduces the fully nonlinear model to a linear one, and the solution at each iteration is obtained by means of the finite element method (FEM). Examples studied were fully cavitating flow past flat plates in a water tunnel. Results are given for pure drag flows past circular and elliptic plates and a lifting flow past a circular plate. Because of the change in flow boundary conditions at the separation edge and the failure of the FEM to resolve these conditions accurately, the ability of the numerical solution to maintain a constant pressure over the entire cavity decreases as the three dimensionality of the free surface increases. However, the present procedure produces absolutely stable iterations and shows no sign of drifting of the free surface. It is found that satisfaction of a tangent separation condition of the free surface from the flat plate body is crucial for the stability of the iterative procedure. Grid refinement in both the streamwise and transverse directions reduces the computational error. While free surface movement between iterations is a useful convergence criterion, a flow-rate balance between upstream and downstream cross-sections appears not to be a good criterion.
