Abstract:The gas and wave's motion in a receiving tube are investigated numerically and experimentally in the present paper. The results show that, velocity of the contact face rises rapidly as gas is injected into the receiving tube, and then drops sharply after a steady propagation. However, velocity of the wave in the tube is almost linear and the wave can be reflected at the close end of the receiving tube. With increasing of inlet pressure, velocity of the wave and steady velocity of contact face also increase. There is obvious thermal effect as the wave sweeps the gas. The reflected wave can heat the exhausting gas in the open end. As an absorber, an expander and a shrink in the tube can almost completely absorb the reflected wave.
