4. Combustion software architecture

The choice of a type of thermodynamic model to simulate the combustion phase in an engine therefore depends on the aim of the study. In the specific context of this dossier, the modeling is intended to be predictive. Its aim is to simulate heat exchange between the combustion chamber and the chamber walls; no modeling of pollutant formation is required. It is therefore natural to adopt a single-zone approach to combustion modelling, which appears to be the simplest to implement from both a scientific and an IT point of view.
