Assessment and Improvement of Fast Euler Solver

Conference paper
Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NNFM, volume 29)

Summary

A generalization of the Fast Solver of G. Moretti [1] for the two-dimensional Euler equations written for generalized curvilinear coordinates is presented. The normalized contravariant base is introduced. The Euler equations are recast in diagonalized form and discretized in time in implicit Δ-form. A system of four pseudo compatibility equations is obtained by means of local one-dimensional analysis. The integration of this system requires the inversion of four bidiagonal matrices instead of 3 × 3 block-tridiagonal matrices. Preliminary results for subsonic flows are presented.
