Measurements made in the oxyhydrogen detonation-driven miniature shock tube. a Typical pressure signals for five different runs of the shock tube operated at an oxyhydrogen fill pressure of 2.5 bar. The pressure sensor is flush-mounted to the inside wall of the driven section at a distance of 12 mm from the end. The driven section is left open to the atmosphere. b The corresponding energies in the shock wave for the five runs. c Time resolved high speed Schlieren images of the blast wave emanating from the open end of the shock tube. The images are acquired at a frame rate of 40,000 fps. d Time-resolved high speed shadowgraph images of the jet of drug ejected through the 300-μm hole. The images are acquired at a frame rate of 51,000 fps. e A velocity-time plot of the tip of the jet as measured from the high-speed shadowgraphy
