Abstract
In order to meet challenging efficiency and emission target, modern engine design is more likely to involve mixed-mode of combustion as well as multiple fuels. In order to accurately predict the process of such combustion in CFD, detailed chemistry based modelling approach is required. This paper introduces the concept of Progress Variable Library Model for Multi-fuel (PVM-MF) Combustion. PVM-MF is designed to model mixed-mode of combustion with multiple fuels while keeping the computational cost low due to the use of the pre-computed libraries. The paper summarizes the application of PVM-MF in four typical modes of engine combustion, namely premixed, non-premixed, compression ignition and mixed mode. The implementation of this model in STAR-CD CFD code is described. To demonstrate the application of the model some IC engine cases are also presented.
