Progress in an experimental and theoretical program designed to investigate a number of important problems in the development of MHD generator channels is described. The areas of reseach include nonuniformity and stability effects, boundary layers, Hall field breakdown, the effects of electrode configuration and current concentrations, and studies of steady-state combustion disk and linear channels in a 6 Tesla magnet of small dimensions. In the area of magneto-acoustic disturbances, a major experiment to study the formation and behavior of propagating waves in a combustion MHD was completed, using the M-2 facility. The results of this experiment are currently being compared with a theoretical model previously developed at Stanford. For the study of the effects of nonuniformities on generator performance, a diagnostic system for measurement of plasma temperature profiles and also a nitrogen injection device were satisfactorily tested in the M-2 flowtrain. An improved laser Doppler velocimeter system for the study of turbulence suppression in a magnetic field has been developed and tested, both on the bench and with the MHD flowtrain. The theoretical model of Hall field breakdown has been modified to better account for the effects of current concentrations. The peg-wall test section of the six-Tesla disk generator has been successfully tested under full thermal and electrical conditions. (WHK)
