Week 3 Challenge : CFD meshing on Turbocharger

Aim

For the given model, check for the geometrical errors to make appropriate volumes. Create and assign PIDs . Perform surface mesh with the given target lengths as per PIDs.

1. Blade stage-1 = 1 mm
2. Blade stage-2 = 1 mm
3. Impeller = 2 mm
4. Shaft rotor = 1 mm
5. Turbo casing = 5 mm
6. Compressor casing = 5 mm
7. Inlet casing cover = 5 mm

Perform Volumetric mesh for the required volumes.
Write a detailed report on your surface meshing & Volume meshing process.

Procedure

• Geometry checkup is ruin looking for intersections/overlapping surfaces , single cons, and triple cones
• Then each errors are fixed seperately by isolating the surfaces
• Surface is mesh is done with given mesh sizes
• Volumes are detected using Define-> auto detect
• Shell volumes are deleted as they dont have any importance in CFD applications
• The inside volumes are then meshed

Learning Outcomes

• Geometry cleanup
• Surface meshing
• Volume meshing

Conclusion

• Volume meshing was done on the given solid
