Numerical modeling of compression ignition engine: A review Suneel Kumar

摘要

Diesel engine modeling draws the greater attention due to its higher efficiency as compared to spark ignition (SI) engine. Still it is very challenging job to model diesel engine due to its complex combustion phenomena. The focus of the present study is to review the different available model used for modeling of Cl engines. The modeling of CI engine is divided into single zone, multizone and multi-dimensional model. Which further subdivided in many submodel i.e. heat transfer, ignition delay period, droplet evaporation, intake and exhaust flow, chemical kinematics and soot formation model. A comparative study has also been carried out with experimental validation to show the compatibility with different modeling approach. Some optimum mathematical input parameter has been suggested by the analysis of different modeling approach to minimize the NOX emission and soot formation to make diesel engine more eco-friendly.
