Turbulence Induced Deflagration-To-Detonation Transition

Abstract

There is a broad desire to unravel the unknown physical mechanisms of turbulence induced DDT. For the implementation of efficient detonation methods in propulsion and energy applications, it is crucial to understand the turbulence characteristics and flow field conditions that result in flame acceleration and detonation initiation. An experimental study is conducted to investigate propagating premixed hydrogen-air flames using a semi-confined square channel with turbulence inducing obstacles. The focus of the study is to observe and analyze the behavior of a fast deflagrated flame with a highly turbulent fluidic jet. Exploring the conditions ahead of a fast deflagrated flame with high levels of compression and turbulence ahead helps expand the experimental database of turbulence-flame interactions and aid in validating existing simulations and theories for assured DDT occurrence.
