Research ArticleOpen accessIn the keywordsA Mathematical Modeling of the Turbulence Combustion Biodiesel in a Compression Ignition Engine: Theoretical FrameworkFrancis Mouzong Bongne, Zacharie Merlin Ayissi et al.The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 30 Sep 2024 · 5,029 accessesView PDF Cite
