Numerical analyses have been performed on liquid-metal MHD flow in a rectangular channel with sudden expansion. The sudden expansion is in the direction perpendicular to the applied magnetic field. Numerical results give negative loss coefficients as was the case of an existing equation based on experimental data. However, the existing equation gives much smaller values (negative but much larger absolute values) than the present numerical analyses. Thus, it is desirable to perform numerical analyses for wider calculation conditions.
