The flow is generated by the rupture of a diaphragm separating a driver gas at high pressure (region 4) from a gas at low pressure (region 1). This rupture results in the movement of a shock wave into the low-pressure gas, and the movement of an expansion wave into the high-pressure gas. The tube length and time period are chosen so that the computation ends before the two waves reflect from the ends of the shock tube. ------------------------|------------------------ P4=1.E6 Pa, T4=20 C | P1=1.E5 Pa, T1=20 C ------------------------|------------------------ Provision is made for the use of the Van Leer higher-order scheme (when HOS = T) and for use of stagnation enthalpy as a variable (when HSTAG = T), but both are defaulted = F.
