1. 1. A high-order artificial viscosity finite element method for the Vlasov-Poisson system

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Junjie Wen; [2023]
   Nyckelord :;

   Sammanfattning : We introduce a finite element method with high-order accuracy for approximating the Vlasov-Poisson system. This method uses continuous Lagrange polynomials as basis functions and employs explicit Runge-Kutta schemes for time discretization. A residual-based artificial viscosity technique is applied for stabilization. LÄS MER

3. 2. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Sammanfattning : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. LÄS MER
