We describe a single-pulse chemical shock tube CST2 established for measuring the reaction rate of chemical reactions and ignition delay for fuels at high temperature along with the procedure for its calibration. The suitability of the facility for measuring the ignition delay is demonstrated by measuring the ignition delay for the ethane–oxygen gas mixture in the temperature range 1250–1611 K by recording the ignition-induced pressure jump and emission from CH radical simultaneously.The results obtained in the present study compare well with the earlier reported values.
