Assignment 11

Challenge 11

1. Tutorial - single cyl DI add case 2 with discretization length 0.1 mm for intake runner and compare with default case 1

The following figures show the tutorial which need to be explored, the PipeRound template, in which the discretization length is defined as a parameter and the case setup where two cases have been tested.

The next figure depicts the simulation results.

2. Explore tutorial no 2 (GEM3D) - “Building intake manifold from STL model”

Firstly, the Intake Manifold is imported as one piece.

Secondly, the model is discretised by curves (different object colour).

Then, a 3-point cutting plan is used to separate the four intakes from the main body.

The following figure shows the pipe conversion of the detailed CAD model part to an estimated geometry.

Then, orifice connection option is used to reduce the sudden step of the geometry.

The next two figures show the implementation of Inlet and Outlet port options

Then, the main body of the intake is converted using pipes and flowsplits.

In the final step, the gaps between the different parts is filled

Then, the model is converted to a 1-D model which is ready to be run in GT-Power.
