Low-frequency rotating spokes are obtained in a cross-field discharge plasmausing two-dimensional numerical simulations. A particle-fluid hybrid model isused to model the plasma flow in a configuration similar to a Hall thruster. Ithas been reported that the drift-diffusion approximation for an electron fluidresults in an ill-conditioned matrix when solving for the potential because ofthe differences in the electron mobilities across the magnetic field and in thedirection of the E$\times$B drift. In this paper, we employ a hyperbolicapproach that enables stable calculation, namely, better iterative convergenceof the electron fluid model. Our simulation results show a coherent rotatingstructure propagating in the E$\times$B direction with a phase velocity of2,500 m/s, which agrees with experimental data. The phase velocity obtainedfrom the numerical simulations shows good agreement with that predicted by thedispersion relation of the gradient drift instability.
