Abstract : The various high-performance shock tube driving techniques considered have been grouped as high pressure/high speed of sound conventional drivers, electric and magnetic field interaction drivers, detonation drivers, and those that derive their flow characteristics from the coupling of energy addition and wave processes in an unconventional manner. 'High performance' can be taken to refer to any property of a shock tube flow that is important to a particular study: for example, shock velocity, driven gas temperature, pressure, and density levels, driven gas kinetic to static energy ratio, and uniformity and duration of the driven gas flow. Data from recent references are compared to determine the relative effectiveness of different driving techniques and the predictability of flow properties. Several fluid dynamic problem areas are outlined; requirements for their study in shock driven facilities are discussed and compared with capabilities resulting from the use of various driving techniques.
