Abstract:
The results of the research work performed to determine the role of blastwaves and mass addition within the reaction zone of spray detonations are summarized. Since most of the findings have been published in the literature, abstracts of the relevent publications have been included. One of the publications describes a model for spray detonations in which the relevant parameters are found to be the ignition delay and the energy temporal variation within the reaction zone. The model can predict the minimum energy for direct initiation when these parameters are known. Recent experiments on laser ignition of fuel drops to simulate the mass addition aspect within the reaction zone are reported in detail. These experiments indicate the mass addition effects are small when compared to the blast wave effects. However, they reveal that, under some conditions, explosive combustion can take place. The experiments appear to be the first of their kind and open up new avenues for research on liquid propellants, fuel-air explosions and detonation transfer.
