| Abstract: | Fluid dynamics simulation was carried out on internal flow field of TBD234 common rail diesel engine's injectors using CFD software,and solid model of the combustion chamber was built,as well spray combustion model.The computational results of internal flow field were set as the boundary conditions of spray model and the spray combustion model was optimized,considering the influence on atomization by nozzle's structure and the flow characteristics of fuel inside the nozzle.The process of spray was picture-t... |
