Abstract : Computer studies of the electric fields and fluid fields in an electrofluid dynamic generator of complex electrode designs are presented. Results of studies are presented for both basic configurations and configurations which simulate real experimental designs. A comparison of experimentally determined I-V curves is made with an I-V curve determined from the computer results. The computed results predicted higher values of current than were achieved in the experimental configuration. The computer studies indicated that the current cut off by breakdown on the inlet nozzle was quite sensitive and that this may account for the difference between the experimental and calculated I-V curves. The results obtained from the basic studies indicate design considerations that could improve the power output of electrofluid dynamic generators. Some results are also presented for the fluid fields in the generator, and a discussion of various fluid flow models is presented. The results presented for turbulent mixing studies indicate the need for a large secondary stream and a value approaching unity for the ratio of the secondary velocity to that of the primary.
