Detonation Dynamics in Thin Channels at Near-Limit Conditions

Abstract

Proposed work will create a high-fidelity numerical representation of an experimental setup in order to perform quantitatively accurate comparison of the numerical detonation models with experimental data. By eliminating various uncertainties associated with initial and boundary conditions, diagnostics, etc., such comparison will show the limits, to which modern thermochemical models are able to reproduce the detonation physics. For the first time such computational-experimental comparison will be carried out systematically for a wide range of realistic fuels. Resulting numerical models will be used to investigate several key open questions related to the detonation properties in near-limit regimes and in conditions representative of realistic detonation systems. Fundamental insights obtained in the course of this work will help advance the understanding of the detonation dynamics in Air-Force-relevant RDRE’s and will aid in the design of practical engines. Addressing these questions is important for improving the accuracy of the numerical models of practical detonation systems.
