The present program aimed to study ignition in nonhomogeneous systems that are of relevance to practical combustion devices. The investigation was conducted in both laminar and turbulent environments, and involved experimental, computational, and analytical components. For turbulent ignition, four specific projects were undertaking, namely 1Characterization of non-reacting turbulent flow fields in counterflow 2turbulent non-premixed ignition experiments 3modeling study of turbulent nonpremixed ignition 4computational simulation of the ignition of an nonpremixed hydrogenair mixing layer with an embedded vortex. In parallel, three projects in laminar premixed and nonpremixed counterflow were explored, especially focusing on the chemical kinetics aspects and the coupling with transport, namely 1 Premixed hydrogenair and propaneair ignition 2 experimental determination and computational calculation of the counterflow ignition temperatures and laminar flame speeds of several C2-C3 hydrocarbons 3 experimental determination and computational calculation of the ignition temperatures of nonpremixed counterflow dimethyl ether DME versus air.
