Space-Time Boundary Elements for Retarded Potential Integral Equations

Produktform: Buch


The philosophy of space-time methods is to treat time and space on equal footing. This work introduces space-time boundary elements for integral formulations of the wave equation in 3+1 dimensions. It is shown that the space-time methodology conforms genuinely to the considered integral operators and facilitates powerful approximation methods.

Hamiltonian Theory of Resonant Transport Regimes in Tokamaks with Perturbed Axisymmetry

Produktform: Buch


Non-axisymmetric perturbations can have a strong influence on the toroidal rotation of tokamak plasmas. This work provides theoretical background and a consistent Hamiltonian description of this phenomenon for plasma species in reactor-relevant low-collisional resonant transport regimes.

Inf-Sup Stable Space-Time Methods for Time-Dependent Partial Differential Equations

Produktform: Buch


Space-time methods are characterised by interpreting the time direction as an additional spatial coordinate. The focus of this work is on space-time variational formulations for the heat and wave equation, which result not only in inf-sup stable formulations but fit also very well to conforming, unconditionally stable space-time discretisations.

Convective turbulent near wall heat transfer at high Prandtl numbers

A modelling approach based on Direct Numerical Simulations and experiments

Produktform: Buch


This work performed Direct Numerical Simulations and experiments on turbulent heated pipe flow at high molecular Prandtl numbers examining the effect of real fluid properties. The acquired insight into the near wall transport of momentum and heat was used for the modelling and validation of thermal boundary conditions applied in RANS simulations.

Experimental and Computational Analyses of Pathological Soft Tissues – Towards a Better Understanding of the Pathogenesis of AAA

Produktform: Buch


In this thesis a novel hypothesis on abdominal aortic aneurysm pathogenesis is proposed. It was derived by the systematic collection of histological, biaxial mechanical and structural data obtained by second harmonic generation imaging and its subsequent evaluation by constitutive modeling and finite element analysis.
