Detonation characteristics of hexane droplets/vapor-air mixtures were determinet on the basis of experiments in a vertical 13-m long detonation tube. Hexane droplets were injected at the top of the test section with generators containing different numbers of needles of 0,8-mm in internal diameter. The droplets moved down and - when first of them reached the bottom of the test section - a initiating shock wave (generated by detonation of oxygen-hydrogen-helium mixture) entered the tube. Pressure histories, shock wave and flame velocities in the hexane droplet suspension were determined on the basis of signals from pressure transducers, membrane switches and photodiodes located along the test section. The results obtained enabled us to state whether and under what conditions a detonation process of the droplet suspension occurs, what are the parameters (velocity and peak pressure) of the detonation wave and how are they affected by the suspension characteristics and the initiating shock wave pressure.
