Fuel Injector CFD Simulation, Three-Phase Flow, ANSYS Fluent Tutorial
This simulation is about a Fuel Injector via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
In general, a fuel injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid so that a lower-pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow.
A steam injector is a typical application of the principle used to deliver cold water to a boiler against its pressure, using its own live or exhaust steam, replacing any mechanical pump.
In this project, a three-phase flow fuel injector has been simulated. This mixture consists o liquid, air, and vapor. The liquid will enter the computational zone through the injector at the velocity of 20m/s, and a jet flow has been formed inside.
The geometry of the present model is drawn by Gambit software. The geometry of this model consists of a combustion chamber, including a fuel injector and an air entrance.
The model is then meshed by Gambit software. The model mesh is Structured, and 932107 cells have been created.
Fuel Injector Method
In this simulation, three fluids are used in the computational zone. These three phases include air, liquid, and steam.
Then the multiphase model is used. Since the separation boundary between the phases is unclear, the mixture model is used. In this multiphase model, the phases are completely mixed. Air is defined as the primary phase, and vapor and liquid as the secondary phase.
Fuel Injector Result
After simulation, the contours of pressure, velocity, and mass fraction of liquid, air, and vapor are obtained. The contours indicate that the liquid flow enters the combustion chamber at high speed and pressure and then spreads completely inside this space.
The contour comparison of each phase of the mixture confirms that the multiphase flow modeling has been performed correctly.
