Summary on Grant Application Form
Combustible mixtures of gases can in general support two steady modes of combustion, namely (slow) deflagration and (fast) detonation. However, there also exist spontaneous processes whereby a slow turbulent deflagration is converted to a fast and very destructive detonation. No method has been developed yet that is capable of accurately predicting a complete turbulent flame acceleration and transition to a detonation event. The proposed research will investigate the change of transition mechanism of propagation and with mechanisms that conspire to cause the formation of detonations in the absence of initially strong energy sources and associated blast waves. The highly non-linear nature of the problem and the large range of spatial and temporal scales call for a combustion of state-of-the-art analytical and numerical techniques, the latter borrowed from the field of computational fluid dynamics. Resolution of the matter will have a significant impact in issues of industrial and domestic safety. The propsed research will bring together scientists from many diverse disciplines and, in a unique way, exploit generic techniques and software that had been originally developed within these distinct communities. The proposed programme could have been put foward as three separate grant applications (from DAMTP, CUED and MMU) but is presented as a single entity in order to epmhasise the crucial need for close interaction between all the parties involved in the research.
