Abstract

Living on a planet with limited resources, more efficient and cleaner combustion is highly desired. Moreover, focus is now on renewable energy. The development of internal combustion engines fuelled by biogas requires both CFD and chemical kinetic simulations. Several detailed chemical kinetic models dealing with the combustion of C1–C3 fuels have been published already. This work uses a selection of these models in COSILAB software assuming treated biogas as methane enriched with ethane and propane, under engine-relevant, lean conditions. The models are compared to each other regarding their performance in laminar flame speed obtained from a one-dimensional freely propagating flame model, and ignition delay time obtained from a zero-dimensional homogeneous ignition process in a batch reactor.
