Modelisation d ecoulements complexes pour des applications aerospatiales

Abstract

This document reports (in French) some achievements performed in the frame of computational fluid dynamics applied to aerospace applications. Different physical issues have been tacled out during several studies focusing on turbulent jets, single phase approach of cryogenic sprays for rocket engines, flows around complex geometries, and hypersonic entry. For each of the different application studied a chapter detailed the related issues and the approach developed. At the end an appraisal for the different topic investigated is done, and potential directions for future activities proposed. This document gives also the state-of-the-art for different aerospace applications in the mid- 2000.
