Numerical Simulation of the Flow in the Fuel Injector in the Sharply Inhomogeneous Electric Field

چکیده
The results of detailed numerical simulation of the flow in an injector including electrohydrodynamic interaction in sharply inhomogeneous electric field formed by electrode system closed to the needle-plane type are presented. The aim of the simulation is to estimate the charge rate flow at the fuel injector outlet. The results were obtained using the open-source package OpenFOAM in which the corresponding models of electrohydrodynamics were added. The parametric calculations were performed for axisymmetric model using RANS k−ω SST turbulence model. Due to swirl device in fuel injector the flow is strongly swirling. To obtain parameters for axisymmetric flow calculations the 3D simulation was performed for the simplified injector model including swirl device and without electrodes.

Pressure fluctuations during fuel injection are one of the factors that negative effect on performance of diesel engine. These fluctuations are caused by the rapid opening and closing of the nozzles and the creation of pressure waves in the fuel rail. One way to control these pressure fluctuations is to change the injector design and use an accumulator in the injector. This study is performed t...
