Research on detonation and explosions

The proposed research program is a continuation of the research that I have been carrying out under NSERC support since 1965. My interest is primarily concerned with the investigation of the detonation, shock waves and explosion phenomenon. The ultimate goal is to achieve a quantitative description of the complex propagation mechanisms of high speed combustion waves and the non steady propagation of shock waves from chemical explosions. The key problems in detonation research is the understanding of the unstable cellular detonation structure. Once a knowledge of the structure is achieved, empirical correlations and analytical theories can be developed to predict the other dynamic detonation parameters of practical interest (e.g. dependence of velocity on the boundary conditions, detonation limits, critical energy for direct initiation, failure diameter, conditions required for the transition from deflagration to detonation, etc.). Quantitative knowledge of the detonation phenomenon is essential for realistic risk assessment of hazardous facilities, and to the prevention, suppression, and mitigation of accidental explosions in the chemical industries, nuclear reactors, energy transportation and storage facilities. Explosion research also addresses the defense needs of Canada. The investigation of the fundamental mechanisms of detonative combustion also contributes to the understanding and modeling of high speed turbulent reacting flows, an area of fluid mechanics which is currently not well understood.
