Abstract : The theoretical research is applicable to a laminar flow regime of the liquid metal in the channel of an MHD generator. These flow conditions can be the working conditions. In addition, at high speeds of the liquid metal the flow conditions can be turbulent. An analysis of the attained solutions has made it possible to establish that during laminar flow conditions of a liquid metal, for a description of the change with respect to time of the integral parameters of the flow, one can successfully make use of a quasi-stationary approximation taking into account frictional forces. This opens broad horizons in the study of transient working conditions of MHD generators during turbulent flow of the liquid metal. In this case it is necessary to deal exclusively with nonlinear equations. Studies showed that a turbulent flow regime of a liquid metal does not influence the character of transient processes in the channel of an MHD generator very significantly. This is explained by the decisive influence of electromagnetic and inertial forces in comparison with forces of friction. (Author)
