Week 4.1: Project - Steady-state simulation of flow over a throttle body

Answer

This geometry is a basic 3D representation of a simple throttle body used in vehicles, which is used to control the air flow towards engine.

We are going to do a basic simulation in converge.

First, we are going to scale down the geometry to about 0.001 of its original size,

For this simulation, the thickness of the pipe is not considered, so we are going to delete the pipe thickness.

Thickness removed.

Now, we are going to close each end of the geometry.

diagnosis check

Boundary defining

Start setting up case tree

The global transport parameter is set to default

Solver is Transient type

Simulation Time Parameter

The Boundary Condition

To find the COG of the throttle body

The Turbulemce model is set as default

The mesh size

The Output Files

To run the simulation we run it in Cygwin

The mesh diagram of the geometry with the fixed embedding is clearly visible around the throttle body. Fixed Embedding is used to get a refined analysis results around the throttle body.

RESULT
