When simulating turbulent flows using Large-Eddy Simulations (LES) or Direct Numerical Simulations (DNS), imposing correct instantaneous flow quantities at the inflow boundary is a challenge. Inflow fluctuations need to preserve the turbulent characteristics of the upstream flow that is not simulated. The inflow conditions are rendered more physically meaningful by rescaling the instantaneous solution from an internal plane normal to the wall located inside the computational domain using self-similarity of the boundary layer velocity profile at each time step of the simulation. Thus the fluctuations at the inflow incorporate correct turbulent structures. This operation enables a reduction of the needed computational domain. This book should be especially useful for researcher in computational fluid dynamics.

Despite efforts of more than centuries, turbulence phenomena is categorized as an unsolved problem. Turbulence is part of everyday's life. The majority of flows of industrial and technological applications are turbulent; natural flows are invariably so. There are many important and interesting physical phenomena which are connected with turbulent flows. Turbulence is observed in natural and engineering applications such as in weather prediction, air pollution, water pollution, aerodynamics and heat exchangers. This work considers an accurate and reliable solutions of turbulent flows. It is concerned with one of the most promising approaches to the numerical simulation of turbulent flows, the subgrid eddy viscosity models. We analyze both continuous and discontinuous finite element approximation of the new subgrid eddy viscosity model. This approach has the advantage that the diffusivity is introduced only on the small scales of the flow. Numerical test shows the new stabilization technique is robust and efficient in solving Navier-Stokes equations for a wide range of Reynolds numbers.

In the distributed environment, it is crucial that during the mesh adaptation process all mesh entities communicating over part boundaries perform correct updates such that the complete mesh remains valid after its modification. This work presents the infrastructure to support parallel mesh modification operations with boundary layers using both simple point-to-point data exchange and interaction with mesh migration. To increase the scalability of large-scale simulations, this study introduces a general-purpose communication package built on top of MPI which is aimed at improving inter-processor communications independently of the supercomputer architecture being considered. The package is developed to support parallel applications that rely on computation characterized by a large number of messages of various sizes, often small, that are focused within processor neighborhoods. The parallel anisotropic mesh adaptation procedures are tested on general curved 3D geometries and appropriately manage the geometrical boundary approximation while maintaining the semi-structured nature of the elements in the boundary layers.

Diploma Thesis from the year 2013 in the subject Engineering - Aerospace Technology, grade: 1,0, Technical University of Munich (Lehrstuhl für Aerodynamik und Strömungsmechanik), course: Computational Aeroacoustics, language: English, abstract: Stretched grids as non-reflecting boundary conditions aim at gradual under-resolution and dissipation of sinusoidal waves and are computationally costly and ineffective if not implemented properly. This defines a need for insight to enable efficient implementation. Two methods of predicting the behavior of sinusoidal waves propagating through stretched grids are presented, an initial value and a boundary value approach. The initial value problem is an approximation and has the advantage that it can be applied with many higher order accurate finite difference schemes. The boundary value problem is more exact but is not applicable for higher order methods. Both methods are verified using a two-dimensional linearized Navier-Stokes solver, which is implemented in the framework of this study. Further, acoustic black hole layers are introduced as an alternative to stretched grids. Using both methods in combination reduces the number of grid points necessary in a boundary domain drastically. All methods are improved with respect to available parameters and their performance is compared using benchmark flows. Explicit recommendations for implementation are developed.

International boundary determination starts with the intention of two or more countries agreed to identified their boundary by a treaty or agreement. Surveying and mapping often play an important role in international boundary determination.The outputs of these boundary determinations are based on static documentation (mapping and reports) for securing knowledge to be attached to the treaties or agreements at the UN, and dynamic documentation (GIS) for their future use. Furthermore one of the important issues in international boundaries is harmonization of the data provided by different sources to ensure consistency, and edge-matching at the boundaries to agree on common representation of the boundary. Standardization of boundary determination can be served best by a set of international standards that integrate a detailed description of the concepts of the boundary geographic information and technology for future use such as those from ISO. The information provided within the boundary determination model can thus be used as a consultation guide to people who may not have the proper knowledge and technical skills in surveying and mapping and in this way may prevent problems.

In this book the solution representations obtained from a recently developed Fokas integral method for solving boundary value problems for linear evolution PDEs are evaluate numerically. In particular, the case of the linear KdV equation is considered. The Fokas method is quite general and it is therefore of wider interest to assess its competitiveness for numerical purposes. Until now pseudospectral methods have been know to be the most accurate numerical scheme for smooth functions. To compare the two methods, the linear KdV equation is computed numerically using both, a pseudospectral method and the direct evaluation of the integral representation. The two methods are compared for accuracy and speed of the numerical computation, showing that for linear evolutionary PDEs the numerical implementation of Fokas method is much faster and more accurate than a pseudospectral method. The nonlinear KdV equation is also looked at using pseudospectral methods and a motivation for a possible hybrid method which would use both the Fokas and pseudospectral methods together is given.

It discusses damage (or defect) prediction in virtual metal forming, using advanced multiphysical and multiscale fully coupled constitutive equations. Theoretical formulation, numerical aspects as well as application to various sheet and bulk metal forming are presented in detail. Virtual metal forming is nowadays inescapable when looking to optimize numerically various metal forming processes in order to design advanced mechanical components. To do this, highly predictive constitutive equations accounting for the full coupling between various physical phenomena at various scales under large deformation including the ductile damage occurrence are required. In addition, fully 3D adaptive numerical methods related to time and space discretization are required in order to solve accurately the associated initial and boundary value problems. This book focuses on these two main and complementary aspects with application to a wide range of metal forming and machining processes. Contents 1. Elements of Continuum Mechanics and Thermodynamics. 2. Thermomechanically-Consistent Modeling of the Metals Behavior with Ductile Damage. 3. Numerical Methods for Solving Metal Forming Problems. 4. Application to Virtual Metal Forming.

This book presents complete and detailed analysis concern elastomers. Some details are given on manufacturing of filled rubber samples, how to perform experimental investigations under different loading conditions, including monotonic and cyclic loadings. Constitutive modeling to model the behaviour of the rubbery materials subjected to a wide range of strain, strain rate, and multiple deformation modes are also presented. To figure out this, a study of modeling of large strain and non-linear viscoelastic behaviour is presented using the available hyperelastic models. The numerical analyses were achieved using the boundary elements method. This book is divided into eight chapters. Chapter 1 is an introductory chapter, chapter 2 presents a historical review of the works in this field. Finite strain or large deformation continuum mechanics has been reported in chapter 3. Chapter 4 presents the theoretical background of the visco-hyperelastic constitutive theories. Chapter 5 presents the numerical analysis using the boundary element methods. Chapter 6 presents a detailed experimental work performed on different types of rubbers. Results & conclusions are presented in chapter 7 & 8.
