AbstractEarly researches on the detonation driven shock tube are reviewed briefly. Calculation results demonstrated that an improvement in attenuation of incident shock wave generated by forward driver can be obtained, provided the diameter of the driver is larger than that of the driven section and an abrupt reduction of cross-section area is placed just beyond the diaphragm and were verified by the experiments. Inserting a cavity ring between the driver and the driven section can make the flow field parameters behind a detonation rather uniform. An additional backward-detonation driver was proposed to attach to primary forward-detonation driver. The Taylor wave in the primary driver can be eliminated completely, if the ratios of initial pressure in additional driver to that in primary driver exceed the threshold value (about 7 times).
