چکیده

A “purely gasdynamic” indirect detonation initiation process is presented that can be independent of diffusion, viscosity and turbulence, and does not require direct initiation. In this process, energy is deposited into a finite volume of fluid in an amount of time that is similar to the acoustic timescale of the fluid volume. Highly resolved two-dimensional simulations show that the artificial diffusion implicit in the numerical method is demonstrated to accelerate detonation formation. It is shown that given sufficient resolution, the detonation formation time becomes dependent only on large-scale gasdynamics and is independent of the small scale structures.

Acoustic Timescale Detonation Initiation in 2-D and its Implications on the 1-D Description

One dimensional numerical simulations of spatially resolved thermal power deposition on the acoustic timescale have demonstrated a mechanism to achieve Deflagration-to-Detonation Transition (DDT) [1, 2]. If the power deposition increases the temperature of a volume of fluid of length l in an amount of time th ∼ ta = l/a, where ta is the acoustic timescale and a is the undisturbed speed of sound...

Numerical Study of Blast Initiation of Detonation Using a Two Step Chemical Kinetics Model

The effect of chemical reactions on the blast initiation of detonation in gaseous media has been investigated in this paper. Analytical method is based on the numerical solution of onedimensional reactive Euler equations. So far, analyses on the blast initiation of detonation have modeled the combustion process as a one-step chemical reaction, which follows the Arrhenius rate law. Previous stud...

Role of the Induction Zone on Turbulence-Detonation Interaction

This paper presents an in-depth analysis on the weak turbulence detonation linear interaction problem. The emphasis is on scaling and resonance issues due to the presence of structural scales that are intrinsic to the post-shock heat release region. Natural frequencies are determined as eigenvalues of the non-forced interaction inviscid problem. Influence of detonation parameters on the set of ...

High resolution GPU-based flow simulation of the gaseous methane-oxygen detonation structure

A gaseous detonation is a combustion-driven, compressible wave propagating at supersonic speeds. Experimental visualizations and numerical simulations confirm that detonation waves have a complex, multi-dimensional, cellular structure generated by various gasdynamic interactions (Ohyagi et al. 2000; Ng and Zhang 2012). Except in special combustible mixtures (such as argon-diluted mixtures) with...
