| Abstract: | The unsteady flow, structure of waves and mechanism of the forming of shock wave in pressure wave refrigerator are investigated in the present paper. An analytical expression of the Mach number of incident shock wave (M s) is derived and by means of which the influences of the incident gas velocity, pressure and expansion ratio on M s are discussed. |

| Keywords: | refrigerator oscillatory tube unsteady flow shock wave |
