Convergence of Chandrashekar’s Second-Derivative Finite-Volume Approximation
Gjesteland, Anita; Svärd, Magnus (Journal article; Peer reviewed, 2023)We consider a slightly modified local finite-volume approximation of the Laplacian operator originally proposed by Chandrashekar (Int J Adv Eng Sci Appl Math 8(3):174–193, 2016, https://doi.org/10.1007/s12572-015-0160-z). ... -
Energy and entropy stable numerical methods with injected boundary conditions
Gjesteland, Anita (Doctoral thesis, 2024-01-26)I denne avhandlingen studerer vi de kompressible Navier-Stokes-likningene formulert med både adiabatiske veggrandvilkår og fjernfeltvilkår. Selv om det er ukjent om disse likningene er velformulerte er de av stor interesse, ... -
Entropy stability for the compressible Navier-Stokes equations with strong imposition of the no-slip boundary condition
Gjesteland, Anita; Svärd, Magnus (Journal article; Peer reviewed, 2022)We consider the compressible Navier-Stokes equations subject to no-slip adiabatic wall boundary conditions. The main goal is to investigate stability properties of schemes imposing the no-slip condition strongly (injection) ... -
SBP-SAT schemes for hyperbolic problems
Gjesteland, Anita (Master thesis, 2019-06-13)Numerical methods for solving partial differential equations is an important field of study, as it helps us to describe many different processes in the world. An important property of a numerical method, is that it should ...
