studentFLUENT - Tutorial Library - SI Engine
SI Engine Schematic.
The purpose of this tutorial is to illustrate the setup and solution of a two-dimensional, four stroke, spark-ignition (SI) engine with port injection.
SI engines are of extreme importance to the auto industry. The efficiency of a SI engine depends on several complicated processes including induction, mixture preparation, combustion, and exhaust flow. CFD analysis has been used extensively to improve each of these processes. This tutorial simulates the intake, compression, expansion and exhaust processes without fuel combustion. Port injection is modeled and evaporation of fuel droplets is simulated. The interaction of the fuel spray with the intake valve is modeled through the wall film modeling features available in FLUENT.
In this tutorial you will learn how to:
- Use of the In-Cylinder model for simulating reciprocating engines.
- Use general strategies for modeling valve opening and closing.
- Use of the Discrete Phase Model (DPM) for modeling port injection.
- Carry out solver setup and perform iterations.
- Examine the results.
- Display and create animations for droplet injection.
