Shock Wave Attenuation in Milli- or Microtubes for Laminar and Turbulent Flow Regime

In an ideal shock tube, the shock wave and the contact surface propagate with constant velocities, and the test time of the hot flow varies linearly along the tube. The hot flow quantities can be easily calculated from the Hugoniot’s relations when the shock Mach number and driven gas conditions are known [1]. But it has been shown that this ideal behavior can be more or less modified function of two main parameters which are the driven gas pressure P1 and the tube hydraulic diameter DH.
