This paper investigates a kind of non-diaphragm shock tube equipped with an innovative and new design valve that is capable of generating well-formed shock waves within a driven tube. Diaphragm shock tubes have the advantage of easy building and instantaneous opening. However, some limitations of this kind of shock tube such as the lack of repeatability without opening, the inability to adjust pressure ratio at a specified interval and the inability to automate the shock tube, caused a development on an automated shock tube. In the non-diaphragm shock tubes, the most important factor is the opening time of the shock tube inlet, which directly influence on the formation and uniformity of the shock wave formed in the driven. In this study, an innovative mechanism to achieve high-speed opening valve with an opening time of eight milliseconds (8ms) is proposed. Absence of any disturbances caused by a change in direction or rotation of gas and the opening from the center to the sides are two unique features of this automated non-diaphragm shock tube. Finally, in this investigation, the functional parameters of this non-diaphragm valve are calculated theoretically and compared with measured experimental data.
