On the Interaction of the Transmitted Shock with the Boundary Layer in a Shock Tube using Argon as Test Gas

摘要

It has been suggested in a previous paper that cooling of the hot gas in the region between the reflected shock and the end plate in a shock tube may result from the bifurcation of the transmitted shock. The reflected shock is the reflection of the primary shock at the end plate and the transmitted shock refers to the shock transmitted as a result of the interaction between the contact surface and this reflected shock. Previous work by Mark and others has shown that where argon is the test gas no bifurcation should occur as a result of the interaction between the reflected shock with the boundary layer for primary shock Mach numbers in excess of 3.
