摘要:A decoupling physical chemical surrogate (DPCS) model was constructed for simulating the multi-component physical and chemical characteristics of practical diesel fuel. In the DPCS model, the physical and chemical characteristics of diesel fuel are surrogated separately, and the physical and chemical surrogates are coupled according to the principles of C/H mass ratio, functional group structure, and carbon balance. By implementing the DPCS model into a Computational Fluid Dynamics (CFD) code, the effect of the multi-component physical and chemical characteristics of diesel fuel on the spray, combustion, and emission characteristics in a constant volume chamber and an optical diesel engine were explored. The results indicate that the DPCS model can satisfactorily reproduce the diesel vaporization and combustion behaviors under wide operating conditions.
