    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tribology; Reynolds equation; Stokes equation; cavitation; FEM; adaptivity; variational inequality; penalty formulation; error estima- tion; residual; duality.;

    Abstract : The main purpose of this thesis is to use modern goal-oriented adap- tive finite element techniques in order to improve the numerical simulation of tribology. Two novel adaptive finite element methods for the Reynolds thin film model, and Stokes model including cavitation are presented and their different strategies are compared. READ MORE

  5. 20. Two Problems on Existence and Approximation Related to the Boltzmann Equation

    Author : Vladislav Panferov; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Boltzmann equation; Povzner type models; diffuse reflection; discrete-velocity models; existence for large data; weak compactness; consistency; convergence; diffuse reflection;

    Abstract : In this thesis, two different types of problems related to the Boltzmann equation of kinetic theory are studied. The first part is devoted to establishing consistency and convergence for discrete-velocity models of the Boltzmann equation. For a new such model, introduced by the author jointly with A. READ MORE
