摘要：

Combustion simulation helps us to predict the pollutant formation and allows us to understand various coupling phenomena of physical and chemical processes. Diesel engine combustion simulation requires models of the spray dynamics, chemistry and heat transfer. The interaction between the chemistry and turbulence is one of the major parameters which had been modelled. Combustion simulation has been carried out by using Computational Fluid Dynamics (CFD). CFD model solves three-dimensional Naiver-Stokes equations with k-ε turbulence model. Combustion simulation has been carried out for one cycle by considering the two strokes compression and expansion with no load conditions. Fuel injection begins at 725°CA ends at 748°CA. Charge motion within the cylinder, turbulent kinetic energy, peak pressure rise, penetration length, and apparent heat release rate were analysed with respect to crank angle. © 2019.
