• The region behind the reflected shock in a shock tube is used as a reservoir of gas for a hypersonic tunnel and in chemical kinetics studies. In order to clarify the gas properties in this region, the interaction phenomenon of the reflected shock with the boundary layer must be made clear. Although many studies have been carried out about this interaction, they are not comprehensive. In this paper, this interaction was observed optically by schlieren method, and the growth rate of the bifurcation and the velocity of the reflected shock were clarified. Furhter, based on the present and previous experimental data, and modifying the previous flow models, a new flow model was presented on the interaction of the reflected shock with the boundary layer. The growth rate of the bifurcation and the velocity of the reflected shock calculated by this model are in fair by good agreement with experimental results.
