Abstract

Abstract

Numerical investigations were carried out to study the phenomena of detonation sweeping a contact surface of inert gas and its decoupling. The control-equations were solved with upwind TVD algorithm and elemental chemical reaction model, with the point-implicit used to overcome the numerical stiffness of chemical reaction source term. The results show that, when detonation sweeps a contact surface of inert gas, interactions of detonation, transmit shock and contact surface take place; in condition of high N2 dilution proportion, detonation is decoupled by rarefaction waves.
