Abstract
(en) The Rapid Compression Machine (RCM) is widely used in the study of auto-ignition phenomena at temperature and pressure conditions similar to those of standard combustion devices such as an internal combustion engine. A reactive and homogeneous mixture is rapidly compressed by a moving piston: the subsequent auto-ignition provides information that help developing detailed chemical kinetics models. The machine-to-machine variability observed in the experimental results is however a key question that needs to be definitely addressed as it is still an active topic of discussion in the RCM community. In this study, CFD simulations first for non reactive investigations, and then coupled to detailed chemistry for the ignition of iso-octane will highlight the strong machine-dependence of RCM experiments.
