Shocks in magneto-reactive-gas dynamics with application to the piston problem; Sur les chocs dans un milieu magnetodynamique reactif avec application au probleme du piston

Abstract

This work deals with detonation and deflagration waves in magnetogasdynamics. Four types of detonations and four types of deflagration are considered. We point out that the propagation of these waves is not always completely determined by the initial boundary conditions and the conservation laws across the discontinuity. To fix the ideas we consider the piston problem and we show that in some cases more conditions must be added to the conservation laws in order to provide sufficient data for the unique determination of the propagation process. We then show that the needed additional conditions may be derived from an investigation of the internal structure of the detonation and deflagration process in magneto gas dynamics. This internal structure is investigated for the eight types of process under the influence of the combustion mechanism and the dissipative coefficients (viscosities, electrical and thermal conductivity). Finally all the possible solutions for the piston problem are discussed in a simple case. The methods developed here may be extended to ionizing shocks.

(author) [French] On considere dans ce travail les ondes de detonation et de deflagration en magneto-dynamique. Quatre types de detonation et quatre types de deflagration sont etudies. On montre d'abord que la propagation de ces ondes n'est pas toujours completement determinee par les conditions initiales, les conditions aux limites et les conditions de choc. Pour fixer les idees nous considerons le probleme du piston et nous montrons que, dans certains cas, des conditions supplementaires doivent etre jointes aux conditions de choc pour determiner l'ecoulement d'une facon unique. Nous montrons ensuite que ces conditions supplementaires peuvent etre deduites de l'analyse de la structure interne des detonations et des deflagrations magnetodynamiques. Cette structure interne est etudiee en tenant compte du mecanisme de combustion et des coefficients de dissipation (viscosites, conductivites electrique et thermique). Enfin on discute de toutes les solutions possibles du probleme du piston dans un cas simple. Les methodes developpees ici peuvent etre etendues au choc ionisant. (auteur)}
