With the advent of super computers during the last ten years, the
numerical simulation of viscous fluid flows modeled by the Navier-Stokes
equations is becoming a most useful tool in Aircraft and Engine Design.
In fact, compressible Navier-Stokes solvers tend to constitute the basic
tools for many industrial applications occuring in the simulation of
very complex turbulent and combustion phenomena. In Aerospace
Engineering, as an exemple, their mathematical modelization requires
reliable and robust methods for solving very stiff non linear partial
differential equations. For the above reasons, it was clear that a
workshop on this topic would be of interest for the CFD community in
order to compare accuracy and efficiency of Navier-Stokes solvers on
selected external and internal flow problems using different numerical
approaches. The workshop was held on 4-6 December 1985 at Nice, France
and organized by INRIA with the sponsorship of the GAMM Committee on
Numerical Methods in Fluid Mechanics.
