Week 3 Challenge : CFD meshing on Turbocharger
Following steps were involved in solving the CFD meshing on Turbocharger.
Step 1: Inputs the downloadedgeometry to ANSA software.
Stap 2: Solving the geometry for single cons. In ANSA workbench I have used TOPO tool to sovle single cons geometry. In TOPO tool I have used Hot points, Cons, Face and etc. Also deleted the overlaped surfaces and unwanted surfaces. Assigne the Inlet and Outlet for both Casing cover and Turbo casing
Refer the below screenshot for the single cons identified in the geometry.
Refer the below screenshot for the single cons solved to the geometry.
Step 3: PID nomenclature. Please refr the below screenshot for the PID nomenclature to the Turbocharger.
Step 4: Following PIDs were surface meshed by the Element type Tria.
1) For Blade Stage 1, Blade Stage 2 and Shaft Rotar given the target length as 1mm respectively, also given the mesh quality criteria of skewness 0.5, Minimum target length 0.5 mm and maximum target length 2mm.
2) For Impeller given the target length as 2mm, also given the mesh quality criteria of skewness 0.5, Minimum target length 1 mm and maximum target length 3mm.
3) For Turbo Casing, Compresser Casing and their inlet and outlets given the target length as 5 mm respectively, also given the mesh quality criteria of skewness 0.5, Minimum target length 3 mm and maximum target length 7mm.
Meshed impeller and shaft mismatch found I have adjested it accordingly to get fin mesh at their intersection.
Please refer the below screenshot of fine surface mesh obtained
Step 5: Finaly after fine surface mesh proceeed with the Volume mesh.
Find the water volume folwing reagions and apply the volume mesh for them.
Please refer the below screenshot for the PIDs for the Volumetric mesh which is highlighted in red box.
Please refer the below screenshot of fine Volume mesh obtained.
Please refer the below screenshot for the section of Volume mesh obtained.
Please refer the below link for the solution of the model.
