A Matrix-Free Locally-Implicit Scheme for Navier-Stokes Equations
Abstract
A locally-implicit scheme for steady-state solution of the thin- layer Navier Stokes Equations is simplified by elimination of coefficient matrices. This reduces both arithmetic computation and computer storage requirements. An added benefit is the simplification of the algorithm which eases the coding task. The locally-implicit scheme uses finite-volume spatial discretization, locally implicit time integration, Jameson-type artificial dissipation terms and a modified Gauss Seidel iteration. The modified method is tested for subsonic and transonic flows over an RAE 2822 airfoil. Thesis.
