Domains of Existence of the Bifurcation of a Reflected Shock Wave in Cylindrical Channels
The bifurcation of a reflected shock wave at the end of a cylindrical shock tube has been analyzed under conditions similar to those neccessary for studying chemical reactions. The experiments have been carried out using shocks in argon, nitrogen and CH4/O2/N2 mixtures. The triple configuration, deduced from pressure signals, has been compared to configurations provided by different models. The polar method has been used to calculate the parameters of the configuration and a method for the estimation of the domain of existence of the reflected shock bifurcation has been proposed.
