Zero-dimensional Plasma Assisted Combustion (PAC) models
Python scripts to compute zero-dimensional constant volume reactors using models for Plasma Assisted Combustion (PAC). Scripts rely on Cantera for the computation of the thermochemistry. Models are based on the work of Maria Castela et al. [1] and Nicolas Barleon [2].

Multi-zone pre-chamber ignition engine model with ignition predicion
A zero-dimensional pre-chamber ignition engine model to assess the influence of geometric or operating point changes on engine operation at a low computational cost [1]. It incorporates a jet ignition submodel based on Direct Numerical Simulation (DNS) results [2] to track misfires. The code relies on Cantera for the computation of the thermochemistry.

Zero-dimensional turbulent jet ignition model
A zero-dimensional jet ignition model to predict the ignition outcome (success or failure) of fresh gases by a jet of hot burnt gases. This model has been derived for pre-chamber ignition engines but can be used for other applications including flameproof enclosures. The configuration is a generic case where a ducted jet of hot burnt gases enters a quiescent atmosphere filled with a premixed charge. The model views the ignition process as the evolution of an open well-stirred reactor convected into the atmosphere, where fresh gases and hot products mix at a certain rate and ignite or not. The code relies on Cantera for the computation of the thermochemistry.
