Hypersonic Flows for Reentry Problems [PDF]

open access: yes, 1991
INRIA and GAMNI/SMAI have organized a Workshop open to the international scientific community on hypersonic flows for reentry problems which was held in Palais des Congres d'Antibes in January 1990 (part I) and April 1991 (part II). This workshop was focussed on the issues of validation of numerical methodolies for the computation of high-Mach number ...
