The fluid behavior and the performance of a pulse-detonation-driven magnetohydrodynamic (MHD) electrical power generator with a diverging-converging nozzle connected to a linear tube are examined by quasi-one dimensional numerical simulations. In particular, the effects of diverging nozzle angle and of linear tube length on the performance are investigated. It is found that the temporal evolution of power output in this MHD generator has two peaks. The first peak is caused by the passage of detonation wave in the MHD generator part, and the second peak is due to the nozzle expansion of the working fluid. Furthermore, the results show that there exists the optimal diverging angle, and the increase in the linear tube length improves the generation performance.
