EXTINCTION AND AUTOIGNITION OF n-HEPTANE IN COUNTERFLOW CONFIGURATION
A study was performed to elucidate the mechanisms of extinction and autoignition of n-heptane in strained laminar flows under non-premixed conditions. A previously developed detailed mechanism made up of 2540 reversible elementary reactions among 556 species was the starting point for the study. The detailed mechanism was previously used to calculate ignition delay times in homogeneous reactors...
متن کاملExperimental and Numerical Investigation of n-Heptane/Air Counterflow Nonpremixed Flame Structure
An experimental and numerical investigation of prevaporized n-heptane nitrogen-diluted nonpremixed flames is reported. The major objective is to provide well-resolved experimental data regarding the structure and emission characteristics of these flames, including profiles of major species (N2, O2, C7H16, CO2, CO, H2), hydrocarbon intermediates (CH4, C2H4, C2H2, C3Hx), and soot precursors (C6H6...
متن کاملAn Experimental Study of Vortex-flame Interaction in Counterflow Spray Diffusion Flames
The extinction behavior of methanol counterflow spray diffusion flames was investigated using a combination of formaldehyde planar laser-induced fluorescence (PLIF) and phase Doppler measurements. Extinction was brought about quasi-steadily, by progressively increasing the flow rates of both oxidizer and fuel side, and unsteadily, by generating a vortex on the oxidizer side. The unsteady experi...
متن کاملEffects of non-equilibrium plasma discharge on counterflow diffusion flame extinction
A non-equilibrium plasma assisted combustion system was developed by integrating a counterflow burner with a nano-second pulser to study the effects of atomic oxygen production on the extinction limits of methane diffusion flames at low pressure conditions. The production of atomic oxygen from the repetitive nano-second plasma discharge was measured by using two-photon absorption laser-induced ...
متن کاملStructure of partially premixed n-heptane–air counterflow flames
To avoid the complexities associated with the droplet/vapor transport and nonuniform evaporation processes, a fundamental investigation of liquid fuel combustion in idealized configurations is very useful. An experimental–computational investigation of prevaporized n-heptane nonpremixed and partially premixed flames established in a counterflow burner is described. There is a general agreement ...
