NUMERICAL INVESTIGATION OF FUEL INJECTORS USING CFX

Abstract

The fuel injectors are vital components of the IC engine that aid in the proper atomization of fuel. The current study's goal is to improve the design of a fuel injection system by changing nozzle dimensions. In Creo design software, and CFD analysis is carried out with ANS YS CFX, the CAD model of the fuel injector is generated. The CFD analysis is performed by RNG k-epsilon turbulence model fuel injection system. The comparison is done for different orifice diameters of fuel injector based on output parameters i.e. velocity, turbulence kinetic energy & pressure.
