The influence of droplet diameter on the detonation characteristics of hexane vapor/droplets-air mixtures was investigated. Hexane droplets were injected at the top of the test section with generators containing different numbers of needles of 0,5-, 0,8- and 1,2-mmin in internal diameter. The droplets were 1,3-, 1,9- and 3,2-mm in the average diameter, respectively. Detonative regimes (with velocities of 1600+-100 m/s and peak pressures rise of 2.5,3.0 MPa) can be initiated in each suspension. The hexane concentration at which the best conditions for detonation initiation and propagation were, as well as the upper limit of detonation increase with increasing droplet diameter.
