UConnRCMPy: Python-based data analysis for rapid compression machines [PDF]
arXiv, 2017 The ignition delay of a fuel/air mixture is an important quantity in designing combustion devices, and these data are also used to validate chemical kinetic models for combustion. One of the typical experimental devices used to measure the ignition delay is called a Rapid Compression Machine (RCM).

Characterization of the reactive flow field dynamics in a gas turbine injector using high frequency PIV [PDF]
arXiv, 2008 The present work details the analysis of the aerodynamics of an experimental swirl stabilized burner representative of gas turbine combustors. This analysis is carried out using High Frequency PIV (HFPIV) measurements in a reactive situation. While this information is usually available at a rather low rate, temporally resolved PIV measurements are ...
