Aim:

To perform the volumetric mesh for the turbo charger model with the given mesh dimensions.

Objectives:

To perform geomtry cleanup for the turbo charger model

To apply surface mesh with the dimensions as suggested.

To convert surface mesh to volumetric metric from the surface mesh.

Procedure:

• Geometry cleanup:

1. Geomtry checks were performed. 
2. Single cons were removed by inserting new surfaces. 
3. Overlapping surfaces were deleted. 
4. Triple cons were left as it is, as they are related to the model. 
5. Property ids were given to all the parts as required. 

• Surface mesh:

1. Different PID's were given different mesh sizes as suggested. 
2. However, near the intersections where different mesh sizes intersect, proper mesh sizes needs to be given using the macros option and topo options. 

• Volumetric mesh:

1. Inappropriate volumes where fluid doesnt flow needs to be removed. 
2. TetraCFD is applied to the Volumes wehere fluid is flowing. 

Result:

Volumetric mesh is created to the turbocharger model.

Conclusions:

• Different parts need different mesh sizes.
• Mesh size is much finer near the intersections of different body parts.
• CFD mesh should given where the fluid is flowing.
