Based on the mechanism of quasi-stationary wave (QSW) formed by optical pulsed discharge (OPD), which is generated by high frequency pulsed laser, a self-compiled computational fluid dynamics program is validated. The results indicate that this program can be used to study air-breathing high frequency pulsed laser propulsion numerically. Impulse coupling coefficients of QSW fluid field based on moving igniting point mode and jet flow mode are both up to about 600 N/MW, which are higher than that of traditional low frequency pulsed laser propulsion (250 N/MW). Advantages and disadvantages of the two modes are compared, and their applicable situation is listed. Moreover, the jet flow mode is easier to realize for mechanism study.
