Diaphragm opening process in shock tubes
Did you know?
WebThe bursting diaphragm produces a series of pressure waves, each increasing the speed of sound behind them, so that they compress into a shock propagating through the driven gas. This shock wave increases the temperature and pressure of the driven gas and induces a flow in the direction of the shock wave but at lower velocity than the lead wave. WebJan 1, 2012 · diaphragm ruptures gradually and the flow evolves from the high pressure chamber to the low pressure chamber progressively. This produces non centered waves in the shock tube and the...
