A Study on Diesel Spray Combustion Modeling by Eulerian and Lagrangian Conditional Moment Closure Models

Eulerian 및 Lagrangian CMC 모델을 사용한 디젤분무연소 모델링에 관한 연구

Numerical simulation is performed to evaluate the conditional moment closure (CMC) models for spray development, ignition, and turbulent combustion for the Engine Combustion Network (ECN) test cases. The CMC model is implemented in the open source code, OpenFOAM, to provide conditional flame structures through the solution of Eulerian as well as Lagrangian conditional transport equations. In spite of more accurate treatment of the convective term, Eulerian CMC provides similar ignition delays and lift-off lengths with Lagrangian CMC.
