Study on the role of low-temperature chemistry in large-molecular hydrocarbon detonation dynamics is of scientific significance not only for enhancement of international impact of our country’s fundamental combustion field, but also of important applicable value in the prevention of explosion safety and detonation propulsion system. The problem involving low-temperature chemistry and cool flame is a frontal science and the role mechanism of low-temperature chemistry on detonation dynamics is lack at present. The project aims to carry out the following works: (1) Effect of low-temperature chemistry on steady detonation structure for large-molecular fuel with and multi-stage ignition behavior; (2) Effect of low-temperature chemistry on detonation initiation for large-molecular fuel; (3) Propagating instability and cellular instability of detonation for large-molecular fuel with low-temperature chemistry. This study is significance of not only the prevention of explosion and the design of detonation propulsor, but also for exploring new mechanism of detonation dynamics and enriching combustion theory.
