A Chimera simulation method and Detached Eddy Simulation for vortex-airfoil interactions
(2011-01-25)The present thesis introduces, verifies and validates a numerical simulation method based on an overset grid (or Chimera) technique that allows to simulate the generation and transport ... -
A Massively Parallel Finite Element Framework with Application to Incompressible Flows
(2011-05-13)The incompressible Navier-Stokes equations describe the flow of Newtonian fluids or gases. They are used in many numerical simulations of flow problems. These simulations have become an ... -
CUDA-based Scientific Computing
(2013-02-12)The first goal of this thesis is the design of SciPAL (Scientific and Parallel Algorithms Library), a C++-based and operating-system-independent library. The core of SciPAL is a domain-specific embedded language for dense ... -
Finite Element Methods with Local Projection Stabilization for Thermally Coupled Incompressible Flow
(2015-09-15)This thesis considers conforming finite element discretizations for the time-dependent Oberbeck-Boussinesq model with a pressure-correction projection scheme of second order in time. Discrete inf-sup stability of the ansatz ... -
Finite-element simulation of buoyancy-driven turbulent flows
(2003-08-25)Turbulent flows driven or significantly affected by buoyancy occur in a variety of problems including building ventilation, cooling of electrical equipment, and environmental science. The ... -
Eine Finite-Elemente-Methode für nicht-isotherme inkompressible Strömungsprobleme
(2011-10-31)In this thesis, various aspects of the implementation of a solver for turbulent non-isothermal incompressible flow problems are considered. This includes in particular a spatial discretization ... -
Ein Gebietszerlegungsverfahren für parabolische Probleme im Zusammenhang mit Finite-Volumen-Diskretisierung
(2007-12-03)The first part of the thesis at hand deals with a finite volume method for time-dependent advection-diffusion-reaction equations. By using dual control volumes based on a common ... -
Generic Programming and Algebraic Multigrid for Stabilized Finite Element Methods
(2007-02-28)Two topics are in the focus of this thesis. On the one hand, the generic construction of efficient data-structures for various purposes in numerical linear algebra, and on the other hand, ... -
GPU fast multipole method with lambda-dynamics features
(2021-11-11)A significant and computationally most demanding part of molecular dynamics simulations is the calculation of long-range electrostatic interactions. Such interactions can be evaluated directly by the naïve pairwise summation ... -
Identification of model and grid parameters for incompressible turbulent flows
(2007-10-24)The present thesis studies the behavior of turbulence models for incompressible flows based on the DLR-THETA-code and calibrates relevant model and grid parameters arising in the numerical ... -
Modellierung turbulenter Strömungen mit Anwendungsfällen in der Bioklimatologie und Astrophysik
(2014-02-06)When on the photo above the west wind Zephyr and in his arms the morning breeze Aura is not floating Venus on the shores of Cyprus , but instead blows out the birthday cake , then his breathing is what is known in fluid ... -
Multistage Algorithms in C++
(2006-04-19)Performance-critical software is rarely implemented in a generic manner. Structural changes usually affect large parts of a project and cause expensive development cycles. Principal reason ... -
Optimizations of Optical Flow Measurement Systems
(2018-10-22)In this cumulative thesis contributions are presented that cover the computational aspects of optical measurement systems for flow investigations in aerodynamics and fluid mechanics. Flow measurements are useful in gaining ... -
