In 16V265H Locomotive Diesel Engine Nozzle Flow Field Simulation Analysis

Abstract:

The investigation of the flow characteristics inside the nozzle becomes more and more important because the flow status in the nozzle and fuel injection significantly influence the emission and economy of diesel engines. Due to limited experimental conditions, we can make use of computer simulation, UG models can be used to predict the flow pattern inside the injectors and promote the level of selection and design of injectors. In this investigation, the UG model is calculated by FLUENT software after considering the compressibility and the viscosity of the fuel. By studying, we can predict the distribution of flow field inside the nozzle, analysis the rationality of the design of nozzle, determine the appropriate boundary conditions, mainly includes the nozzle pressure chamber and the needle tip structure, points out that the improvement direction.
