Chemical Kinetics and Aerodynamics of Ignition
Abstract
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: (1)Characterization of non-reacting turbulent flow fields in counterflow; (2)turbulent non-premixed ignition experiments; (3)modeling study of turbulent nonpremixed ignition; (4)computational simulation of the ignition of an nonpremixed hydrogen/air 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 hydrogen/air and propane/air 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.
