Popis:	An unsteady expansion wave was generated through rupture of a secondary diaphragm by an incident shock wave in a shock tube to study the three-body recombination of iodine atoms. The application to chemical reaction studies has been made possible through an extension of the usable flow time, and a theoretical treatment enables the effect of coupling of chemical reaction to gas flow to be taken into account. Species concentrations along different particle paths in the expansion wave are given to show the three types of flow regime (frozen, nonequilibrium and equilibrium) which can be accessed by this technique. Using these results, theoretical and experimental I2 concentration profiles are compared as a function of time in the nonequilibrium regime.
