WebYou obtain three types of features: Shock: sharp discontinuity in fluid variables, physically admissible only if there is an entropy increase through the shock Rarefaction fan: occurs instead of shock when there is no entropy increase through shock Contact discontinuity: discontinuity in density only. It advects passively. WebIn his experiments he divided a cylindrical tube into two parts by a diaphragm and obtained a discontinuity (shock wave) with a speed over 600 m/s by rupturing the diaphragm with a high-pressure gas that was supplied into one side. This type of facility is still used at present as a fundamental type of a shock tube (Fig. 4.1.1). The effect of ...

Web16 Jul 2013 · 'the pressure drop across the shock wave in choked flow cannot be calculated directly. The only recourse is to use the choked flowrate as a new boundary condition on the pipe downstream of the shock wave.' ... and again understand how I deal with the pressure discontinuity that will occur at the reducing T-piece junction with the common 4 ... WebA simple shock tube is a tube, rectangular or circular in cross-section, usually constructed of metal, in which a gas at low pressure and a gas at high pressure are separated using some form of diaphragm. See, for instance, texts by Soloukhin, Gaydon and Hurle, and Bradley. [6] [7] [8] The diaphragm suddenly bursts open under predetermined ... federal employee retirement fehb
