Week 3 Challenge : CFD meshing on Turbocharger

CFD MESHING ON TURBOCHARGER

OBJECTIVES:

1.Check geometrical error

2.Create and assign PIDs

3.Perform surface mesh with given target length

4.Perform Volumetric mesh

1.CHECKING GEOMETRICAL ERROR:

Deleting pink colour surface which is patched or overlapped

 Making all the single cons to double cons

After cleanup all the single cons,triple cons to double cons. Keeping some triple cons for specifically needed.

2.CREATION AND ASSIGNING PIDS:

 After renaming for assigned PIDs,

3.SURFACE MESH:

For blade1,blade2,shaft rotor = 1mm

Minimum size:0.7mm

Maximum size:1.3mm

For Impeller = 2mm

Minimum size:1.7mm

Maximum size:2.3mm

For Turbo casing,Compressor casing,Inlet casing cover =5mm

Minimum size:4.7mm

Maximum size:5.3mm

 

4.VOLUMETRIC MESH:

As the meshing is internal flow, focusing on where flow is significant. Volume meshing is done with Tetra CFD mesh
