| Abstract: | The contact face and shock wave motion in an open ends receiving tube of gas wave refrigerator are investigated numerically and experimentally.The results show that, velocity of the contact face rises rapidly as gas is injected into the receiving tube,and drops sharply after a steady propagation.However,velocity of the shock wave in the tube is almost linear.With increasing of inlet pressure,velocity of the shock wave and steady velocity of contact face also increase.In addition, time and distance of contact face propagation in the receiving tube become longer. |
