  1. 1. Including Finite Larmor Radius Effects on RF Heating of Fusion Plasmas using Weak-Form Contributions in COMSOL

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jonas Christ; [2022]
    Keywords : plasma; fusion; RF; radio frequency; IBW; FW; ion Bernstein wave; fast wave; simulation; FEM; finite element method; Taylor; Taylor expansion; COMSOL; MATLAB; FLR; finite larmor radius; magnetized plasma; hot plasma; thermal plasma; plasma; fusion; radiofrekvens; simulation; FEM; finita elementmethod; Taylor; Taylorutveckling; COMSOL; MATLAB; FLR; ändliga Larmorradie-effekter;

    Abstract : In a fusion plasma, the ions have to be heated to reach fusion relevant temperatures. One possibility is to launch an electromagnetic wave in the radio frequency band into the plasma. This wave can resonate with the ions at their cyclotron frequency and hence, the method is called ion cyclotron resonance heating. READ MORE

  3. 2. A predictor corrector method for a Finite ElementMethod for the variable density Navier-Stokes equations

    University essay from KTH/Numerisk analys, NA

    Author : Isabel Haasler; [2017]
    Keywords : ;

    Abstract : Constructing Finite Element Methods for the incompressible Navier-Stokes equations that are computationally feasible requires the use of pressure segregation methods such as the predictor corrector scheme. From an algebraic point of view these methods correspond to a preconditioned Richardson iteration on the pressure Schur complement. READ MORE

  4. 3. Design of slender steel members : A comparison between the reduced stress method and the effective width method

    University essay from KTH/Bro- och stålbyggnad

    Author : Oskar Skoglund; Daniel Samvin; [2016]
    Keywords : Steel structures; finite element method; reduced stress method; effective width method; nonlinear finite element method; Stålkonstruktion; finita element metoden; reducerad spänningsmetoden; effektiva bredd metoden; olinjär finita element analys;

    Abstract : As of now, the most common way in Sweden, to address the issue of local buckling of steelstructures is through the procedure called the effective width method. A less commonprocedure for dealing with local buckling is the reduced stress method. READ MORE
