Solving a Port Flow Simulation in IC Engine

Solving a Port Flow Simulation in IC Engine

In this tutorial of port flow analysis, you will measure mass and angular momentum flux (swirl and tumble) for given cylinder head and intake port design over varying valve lifts of 2mm, 6mm and 10mm. You will create swirl monitor planes at 30 mm, 45 mm, and 60 mm below the cylinder head. The inlet, outlet and wall boundary conditions are as shown in the  Figure Problem Schematic. Initial conditions are pressure 101325 Pa and temperature 300 K.

Port Flow Simulation

The tutorial illustrates the following steps in setting up and solving a port flow simulation of an IC engine.
• Launch IC Engine system.
• Read an existing geometry into IC Engine.
• Decompose the geometry.
• Define mesh setup and mesh the geometry.
• Add design points to observe the change in results with change in input parameters.
• Run the simulation.
• Examine the results in the report.

This tutorial is written with the assumption that you are familiar with the IC Engine system and that you have a good working knowledge of ANSYS Workbench.
