On “transcritical” and “hypercritical” flows in magnetogasdynamics
The existence of smooth flows in transonic, transAlfvenic, and hypercritical regimes is determined. The flow behavior in the hypercritical regime is, in general, regular for the case gamma =2. Phenomena associated with the flow of a highly conducting gas in the presence of a strong aligned magnetic field are exemplified in two simple solutions. (L.N.N.)
