Week-11 : Discretization of 3D intake manifold using GEM-3D

Discretization of 3D intake manifold using GEM-3D

Aim:

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

• • Parameters-Torque, BSFC, max cylinder pressure
  • simulation time

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

Intake Manifold:

Volume:

The STL file is opened in GEMS 3D.

The four exhaust of manifold is divided into sub-parts.

The unevenly curved outlets are turned into pipes.

The manifold is exported into the GT model:
