Abstract
This work was performed in order to investigate the influence of an axial magnetic field on the flow properties and heat-transfer characteristics of a partially ionized gas in a cylindrical flow channel. A description of the plasma generator and test channel is given along with experimental results for heat-transfer measurements at the channel wall and flow conditions within the channel as a function of field strength. Data obtained show a heat-flux reduction to the walls of the order of 20 per cent for a field strength of 20 kilogauss with indications that the interaction is limited to the boundary-layer region.
