Experimental characterization of ignition events in CVC like conditions

This
work focuses on investigating the sensitivity of the minimum ignition energy ( to both mixture (C 3 H 8 / and flow properties in a
constant volume chamber ( Tumble 2 The study involves analyzing the flow average velocity using high speed PIV, starting from inert mixtures Additionally, experiments are conducted in the reactive case using coupled PIV/OH PLIF techniques to measure, identify, and follow the fresh gas velocity and the contour of the ignition kernel in propane/air mixtures. The research aims to determine the MIE while controlling the mixtures and flow properties in the CVC chamber, using time resolved high speed PIV to determine the velocity field in the chamber, and PLIF to measure the turbulence intensity of the fresh gas velocity and the contour of the ignition kernel in propane/air reactive mixtures
