Numerical simulation of burning methane on S195 diesel engine

摘要

The numerical simulation was carried out by building methane-diesel fuel model at the base of physical model and basic control equation of hydrodynamics, by adopting non-premix combustion method, by simplifying combustion as blends, and by calculating blend fraction. Furthermore, its combustion press field, temperature field and velocity field were analysed. Finally, the experimental results indicated that the model could exactly simulate the combustion process at the S195 diesel engine.
