On the Eulerian AFTON Equations for Axisymmetric Fluid Flow,

Abstract

The AFTON codes are based on a method for constructing finite difference equations that describe the evolution of classical fields, and more particularly on the continuum-motion equations that follow from the method for the common cases of flow symmetry. Axisymmetric fields of motion are computed by the AFTON 2A code, one of whose versions has been specialized for solution of the time-dependent Navier-Stokes equations for compressible flow, in Eulerian form. The version of AFTON 2A in question has now been used to compute many viscous compressible flow fields. This report discusses the following topics: Finite difference meshes and zones in AFTON 2A; Continuum equations for mass, momentum and energy conservation, and the internal energy relation; AFTON 2A finite difference equations of motion.
