A numerical study of the nonuniform loading of a segmented MHD channel
Abstract
The characteristics of an MHD generator are analyzed given nonuniform loading of various segments. In making the analysis, the numerical solution to the twodimensional problem of the distribution of the current and potential in a segmented MHD channel having a nonuniform flow of an anisotropically conducting plasma is used. Two cases are considered. In the first, the load parameters in one of the segments of the channel's working section vary while the other segments are subjected to fixed equilibrium loading. In the other, the external load parameters in a uniform section of the channel vary synchronously; here, each of the loads is connected to two segments the adjacent electrodes of which are joined through equal ballast resistors. The results of the numerical experiment are used in constructing voltampere characteristics for channel segments subjected to nonuniform loading. Attention is given to certain features of the various methods used in regulating external loads.
