Extension of methods based on the stabilized finite element formulation for the solution of the Navier–Stokes equations and application to aerodynamic design

Abstract

Accurate and fast simulation-based processes are key to the design of future aircraft. Computational Fluid Dynamic technology at Dassault Aviation relies on numerical formulations developed by T.J.R. Hughes. Continued efforts over the past years have led to impressive capability and new tools that are applied to the design of both long-range business jets and military aircraft. Recent advances are related to multidisciplinary design technology and to complex flow physics associated to turbulence and transition phenomena. This paper will present a number of examples to illustrate these new capabilities. Methods developed for the flutter analysis of configurations with complex flow features will be discussed. Aerodynamic simulations required for structural fatigue analysis will also be presented. Finally, complex thermodynamics capabilities will be illustrated.
