摘要：

This study investigates the minimum ignition energy (MIE) measured in a constant volume chamber (CVC), specifically examining its sensitivity to variations in both mixture compositions C3H8/air/residual burned gas (RBG) and flow properties. To gain a comprehensive understanding of the ignition process, the average velocity of the flow is investigated using time-resolved high-speed Particle Image Velocimetry (PIV). The experimental setup involves the examination of inert mixtures followed by reactive mixtures of propane/air/RBG, with PIV techniques employed to identify and track critical parameters such as the fresh gas velocity and the contour of the ignition kernel. By exploring the influence of mixture compositions and flow properties on MIE, this research contributes to the fundamental understanding of ignition phenomena in confined environments.
