A shock tube method in the kinetic study of nonequilibrium ionization-recombination by rarefaction wave cooling
A shock tube method is introduced to study the ionization-recombination kinetics of high temperature gas, in which a test gas is heated and ionized by a reflected shock wave and subsequently quenched by a strong rarefaction wave reflected on the end wall of the driver section as the main cooling wave associated with a rarefaction wave incident back into region 5 when the reflected shock wave interacts with the contact surface. As the quenching rate of the strong rarefaction wave reaches 106K/s, a nonequilibrium ionization-recombination process occurs, during which the ion recombination with electrons dominates.
