✦ Synopsis

In the present work the multigrid strategy is applied to second-order EN0 schemes for the computation of steady compressible flows. The performances of the algorithm are analysed in many flow situations, ranging from low subsonic to high supersonic flows, for both internal and external problems. Three different Riemann solvers were considered in the study of computational efficiency and solution accuracy.
