Turbocharger geometry cleanup & volumetric meshing

Objective:

Our objective is to convert the turbocharger model into the clean model ,optimized and meshed for CFD usages.

Procedure:

Turbocharger Model :

The above diagram is a error model where we have to do the topology. We have to convert the single and triple cons to double cons. That glitching shows beacuse of faces shared. For that use the inot option and delete that common surface

The wireframe model shows the perims. By using the topo, intersect and project option, the single and triple cons are converted into the double cons. Still there is some triple cons because of the model designed in a way.

The above two diagrams are topologied. Set the particle PID and convert the shaft and volume into the single volume for the volume meshing.

Surface Mesh:

Here tria elements are used.Tria elements have high accuracy and the area patched with the meshes in different length. By using Perimeter- length option we can easily increase or decrease the element size.

After do the surface mesh we have to do the volume mesh. For volume surface mesh is necessary.

By using define option create the control volume and then the control volume is going to mesh by tetra CFD.

By using the topo mode we can easily convert the error model into error less and do the mesh in mesh mode for surface mesh and then the volumetric mesh is generated.

Conclusion:

For cfd purposes, we use the TETRA CFD for volume meshing and the control volume is necessary where fluid flow take place.
