  3. 2. Finite Element Approximations of 2D Incompressible Navier-Stokes Equations Using Residual Viscosity

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : William Sjösten; Victor Vadling; [2018]
    Keywords : Finite element method; incompressible Navier-Stokes equations; residual based artificial viscosity; stabilization; adaptive method; Chorin s method; IPCS; Crank-Nicholson s method; benchmark problems; CPU-time; accuracy;

    Abstract : Chorin’s method, Incremental Pressure Correction Scheme (IPCS) and Crank-Nicolson’s method (CN) are three numerical methods that were investigated in this study. These methods were here used for solving the incompressible Navier-Stokes equations, which describe the motion of an incompressible fluid, in three different benchmark problems. READ MORE
