Title

Reflected-Shock Ignition Of Syngas At Engine Pressures And Comparison To Kinetics Models

Abstract

Shock-tube experiments were performed for synthesis gas mixtures at engine pressures, a region where not much data are currently available. Ignition delay times were obtained for two mixtures, one consisting of mostly CO/H2 and one of H2 only, for temperatures ranging from 971 - 1277 K and pressures up to 30.8 atm. Ignition delay times were determined using pressure at an endwall location, with emission from the hydroxyl radical A2∑+ → X2π transition near 307 nm used for further interpretation of results. Two state-of-the-ar chemical kinetics models were compared to the experimental data. The models were in good agreement with the data above 1100 K for all mixtures, however at lower temperatures the models greatly over predicted ignition times, in some cases more than one order of magnitude. This result is important in fields such as power generation, where syngas is used as a fuel in gas turbines. Copyright © 2008 by the Authors.
