Propagation and reflection of gas waves in a close tube

摘要：

The gas and shock waves motion in a receiving tube is 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 and the shock wave can be reflected at the close end of the receiving tube. With increasing of inlet pressure, velocity of the shock wave and steady velocity of contact face also increase. There is obvious thermal effect as the shock wave sweeps the gas. The reflected shock wave can heat the exhausting gas in the open end. As an absorber, a expander and a shrink in the tube can almost completely absorb the reflected shock wave.
