Application: Detonations

Abstract Detonation is a shock-induced combustion in which chemical reactions are closely coupled with shock waves. The wave compresses the reactant an abrupt increase temperature and pressure, initiating reactants to be burnt into products. intense heat release permits high propagating speed of sustained. It fundamental research related both safety industry propulsion systems. For most explosive mixtures, detonation speeds formulated by Chapman–Jouguet (CJ) theory. Typical velocities for gaseous mixtures generally range from 1400 3000 m/s. Behind shock, time scale commonly on order microseconds or even less. Furthermore, front intrinsically unstable, forming transient multi-dimensional structures. Many studies revealed that resolution necessary resolve essential Due its complex nature multiple scales, thus challenging problem solvers shock-capturing capability, robustness, computational efficiency. This chapter will present several aspects applying CESE schemes.
