Week-11 : Discretization of 3D intake manifold using GEM-3D
AIM:
1. To explore tutorial- single cyl DI Engine with discretization length 0.1 mm for intake runner.
2. To explore tutorial no 2 (GEM3D) - “Building intake manifold from STL model”.
(1) Single cylinder Diesel Ignition Engine:



Case setup:

two cases with different Discretization Length were used at 3600RPM.
Results:






Conclusion:
| Discretization Length (40mm) | Discretization Length (0.1mm) | |
| Torque(N-m) | 96.2 | 95.9 |
| BSFC(g/kW-h) | 238.2 | 238.9 |
| Max.Cyl Pressure(bar) | 117.11 | 115.18 |
(2). Exploring 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:
