摘要: Conditional Source-term Estimation (CSE) is a turbulent combustion model that uses conditional averages to close the chemical source term. Previous CSE studies have shown able predict flame characteristics successfully; however, these only focused on simple hydrocarbon fuels mostly composed of methane. The objective present paper evaluate capabilities applied non-premixed methanol flames, which has never been done previously. current study investigates two different types flames: piloted and bluff-body flames. For flame, standard k–e used for turbulence modelling, while Shear Stress Transport (SST) k–ω case. Different values empirical constants within models were tested, it was found Ce1 = 1.7 γ2 = 0.66 provided best agreement with experimental measurements mixing ...
