A New Diaphragmless Shock Tube Facility for Interface Instability and Mach Reflection Studies
A new shock tube facility has been constructed in order to help clarify: (i) the exact nature of Mach reflections in density stratified media and (ii) the growth rate of the interfacial instability under forcing by a shock wave. The shock tube is diaphragmless and has two fast-action valves at each end of the driven section, one to create a well defined interface between two dissimilar gases and the other to produce a shock propagating into the interface. Actuation of the two valves is pneumatically synchronized. The shock tube operates in the Mach number range of 1.01 to 5 with an exceptionally high degree of reproducibility and rapid turn-around time. The design, construction and performance studies of the shock tube are presented.
