Inflation problem: Internal pipe flow with Turbulator Inserts
Hi, members! I'm new to both ANSYS-CFX and this highly informative and respected forum. Please pardon me if my inexperience comes off as ignorance.
I'm trying to simulate heat transfer to water flowing inside a copper absorber tube with turbulator inserts. The details are:
Inner Dia: 1 inch
Outer Dia: 1.125 inch
Turbulator thickness: 1 mm
Here's the model part showing the turbulator profile:
..and the standard 3-view sketch:
Several of these parts have been assembled to a length of 1 meter:
Min size: 1.E-4
Max face size: 5.E-3
Max tetra size: 5.E-3
During meshing, the mesher displayed an error of inflation layers clashing with the body mesh. It says: "The Patch Conforming Tetrahedron Mesh failed due to intersection in boundary or inflation mesh Here is a picture of the resultant mesh (Mesh of outer pipe is hidden):
Front view (Notice the lack of inflation):
I have the following questions:
1. How do I tweak the inflation layer to adjust itself near the turbulator tips?
2. The Copper pipe was also meshed under the default setting of CFX physics preference. Will that create a problem?
