Abstract

The difficulties to be faced when attempting the numerical description of an inviscid compressible flow are mainly related to the treatment of discontinuities and to the discretization of complicated geometries. Different ideas and approaches are available: briefly, shock capturing or shock fitting as regards the treatment of discontinuities, numerical or algebraic or analytical body fitted grid generation as regards the geometrical discretization.

The present work is based on a peculiar use of a shock capturing technique and on an adaptive grid generator, each other related. The main questions addressed in the paper are the following:
  1. 1)

    what is the capability of upwind numerical processes on modelling multidimensional flow fields;

     
  2. 2)

    how the grid affects point (1) and, as a consequence, what kind of grid has to be used.
