  2. 6. Uncertainty Quantification and Numerical Methods for Conservation Laws

    Author : Per Pettersson; Jan Nordström; Gianluca Iaccarino; Gunilla Kreiss; Rémi Abgrall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; polynomial chaos; stochastic Galerkin methods; conservation laws; hyperbolic problems; finite difference methods; finite volume methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets.

  4. 7. Uncertainty quantification for wave propagation and flow problems with random data

    Author : Markus Wahlsten; Jan Nordström; Per Pettersson; Rémi Abgrall; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we study partial differential equations with random inputs. The effects that different boundary conditions with random data and uncertain geometries have on the solution are analyzed. Further, comparisons and couplings between different uncertainty quantification methods are performed. READ MORE

  5. 8. Development of a Multidimensional Residual Distribution Solver for Large Eddy Simulation of Industrial Turbulent Flows

    Author : Doru Caraeni; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; High-Order Compact Schemes.; Compressible Flows; Parallel Computations; Multidimensional Residual Distribution Schemes; Large Eddy Simulation; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : This thesis presents the results of the author's research activity to develop a time-space accurate flow-solver for Large Eddy Simulations (LES), based on the Multidimensional Residual Distribution approach. The aim of this work is the attempt to develop a compact high-order algorithm which includes multidimensional flow physics, in hope of creating a better algorithm for LES of turbulent compressible flows.

  6. 9. Studies of reursive projection methods for convergence acceleration of steady state Calculations

    Author : Joakim Möller; KTH; []
    Keywords : ;

    Abstract : this paper we have defined two classes of projectionmethods. RPM(m) and NPGS(m), where RPM(1) is the classicalscheme due to Shroff \&Keller. Following the ideas in Lustet al., we obtain NPGS(m). READ MORE
