Flow transient in MHD linear channels are analyzed by means of a quasi-one-dimensional time dependent model. Medium size MHD channelsboth in segmented Faradayandin diagonal connection are utilized for the present study. Plasma flows derived from the natural gas combustion with a mass flow rate of 25 kg/s in the subsonic regime and with a mass flow rate of 45 kg/s in the supersonic regime, are considered. Transients generated by the transition from the nominal operating condition to short circuit, by the transition from the nominal operating condition to open circuit and by a sudden interruption of the seed supply are analyzed.
