Abstract
Numerical simulations are used to study detonation transfer between gaseous explosive layers. The computations solve the time-dependent two-dimensional Euler equations coupled to a two-step induction-parameter model of the chemical reactions. The problem considered is the interaction between a detonation propagating through an argon diluted hydrogen-oxyten mixture and a secondary layer that is either more dilute, less dilute, or the same as the primary mixture. The initial interaction between the two layers results in the propagation of an explosive bubble or blast wave into the secondary mixture. After the blast reflects from the bottom wall of the secondary-detonation tube, it either decays or initiates a detonation in the secondary mixture, depending on the specific secondary mixture. The calculations show that when the secondary explosive is more dilute, the primary detonation first decays but then is reinitiated by an explosion induced by shock reflection behind the primary wave. Simulated pressure transducer outputs were in excellent agreement with experimental pressure traces.
