A feasibility of improvement in performance of a disk CCMHD generator with electromagnetic diffuser is investigated with two-dimensional numerical simulation where the development of boundary layer can be clarified. Mach number at the exit of electromagnetic diffuser can be controlled by the load resistance connected between the electrodes equipped in the electromagnetic diffuser. By optimizing the load resistance, the total enthalpy extraction ratio and adiabatic efficiency can be improved. This is ascribed to the fact that the additional power output can be obtained in the electromagnetic diffuser without a change in the total pressure at the exit.
