抄録

The authors newly develop a two-dimensional design calculation code of supersonic nonequilibrium disk MHD generators which takes the effects of the boundary layer into consideration. Since the electric field strength usually takes almost the same value in both the main flow and the boundary layer, constant electric field strength is adopted as a supplementary condition and the design calculation on the plane including the boundary layer without dividing the flow into the main flow and the boundary layer is realized by applying this condition all over the generator. It can determine the actual generator configuration and detailed two-dimensional quantity distributions including the boundary layer. As an example, a supersonic nonequilibrium disk MHD generator with 50 MW thermal input and 15 MW electrical output is designed by the new two-dimensional design calculation code. Accuracy and necessity of the code are confirmed by comparing the results with the two-dimensional time-dependent simulation results and with the quasi-one-dimensional design calculation results.
