An Experimental and Kinetic Modeling Study of Ethanol / Dme Mixtures Auto-Ignition

A high-pressure shock tube characterization and auto-ignition delay investigations

International audience; A high pressure shock tube “HPST” has been designed for the purpose of chemical kinetics studies at elevated pressures and temperatures. The present HPST is designed as a versatile tool and includes the features of a fast compression, optical accessibility, and capability for specie measurement. Characterization experiments establish the suitability of the tube for chemical kinetic studies and show that highly repeatable experimental conditions up to 40 bar and temperatures between 1300 and 2000 K can be obtained. As well, tailoring gas mixture in the driver section, used to obtain a longer test time, is studied in the characterization experiments. Using this facilit…
