Summary on Grant Application Form |
|
Detonation waves are violent and powerful combustion waves. The power of such waves may be harnessed for use in propulsion devices or explosives, while unplanned detonations represent an extreme explosion hazard. Understaning a how detonations are ignited, propagate or fail is crucial for controlling such processes in engineering applications and explosion safety (e.g. detonation wave engines, anti-terrorism, etc.).In real fuels such as hydrocarbon mixtures, hydrogen-oxygen mixtures and condensed phase explosives, the chemistry governed by chain-branching reaction kinetics. While the majority of previous work on detonation theory used a simple single reaction chemistry model, such a one-step model does not properly describe detonations in chain-branching fue The purpose of the project is to use and develop a generic chain-branching kinetics model in order to investigate detonation ignition, propagation and failure in such fuels, including aspects of deflagration-to-detonation transition. This will be achieved by using an integrated approach of mathematical analysis and numerical simulations. The results will b compared and contrasted with the predictions of the single-reaction theory.The results will not only extend fundamental detonation theory, but should also be of use in engineering design and control of detonation processes.
