オリフィスのある衡撃波管内の流れ

The effect of orifice located in a shock tube is studied experimentally by using pressure probes, and a characteristics method is applied to solve the flow field by taking the experimental orifice condition into account. The orifice condition used is derived from a modified JENNY's formula for the pressure drop, with the additional mass and energy conservation equations. The results show that calculations including the effect of orifice agree with the experimental pressure variation.
