The Simulation Of Spray In Engine

The capability of combustibility and emission according with the spray system in direct spray engine has been described in theory in this paper. The paper build some formulation about spray hole in spray system base in hydrokinetics, witch supply initial conditions for computing the spray-field. Building the model of fuel bundle is the core in this paper, because of the complexity and essence of the spray, the paper has disport the full process model with some models: drop model, vaporize model, breakup model etc. The paper use CFD method to research the models and supple the mathematics base. Finally, using FIRE, which designed byAVL, simulate the spray and combustibility of two stroke direct engine.
