Paper Abstract

An oil film detonation experiment was conducted in a rectangular shock tube with a thin layer of n-octanol coated on the bottom wall of the tube as a nonvolatile fuel and with gaseous oxygen in the tube as the oxidizer. The film detonation was initiated by a shock wave generated by the gas phase detonation of a H2 - 02 mixture in the driver chamber separated from the main shock tube by a thin mylar sheet. Piezoelectric pressure transducers were employed for the detection. The propagation velocities and the pressure ratio of detonation wave to the driving shock wave were determined from the recordings of the transducer outputs. The wave structure and the propagation process of the film detonation were investigated by means of high speed schlieren photography with a framing rate of 2x105fps.
