Dear collegues.

I am calculating tip clearance flow in axial type turbomachinery. Because I used the low Reynolds number turbulence model, very dense grid with clustering near the wall is needed. I tried to generate mesh bu using commercial package, but I could not obtain any satisfactory results. Therefore, I determined to order the package and, if possible, please let me know your suggestions.

Thank you

If you need a high quality (hex) mesh with suitable spacing at the wall then you should have a look at GridPro.

There is also Tiger from Catalpa. You can download even a demo online and test if it is suitable for your application

IGG/Autogrid from NUMECA can certainly help you. This meshing tool is specifically dedicated to turbomachine and tip clearance modelisation can be performed.

The meshing tool IGG/Autogrid from NUMECA will help you a lot. It is dedicated for meshing on turbomachines and affords to modelize tip clearances.

TascFlow from AEA Technology is designed for turbomachinery.

Hello,

You could also look at ICEM CFD HEXA. For more info see,

"G/Turbo", a new preprocessing tool from Fluent is specially designed for Turbomachinery applications. It allows modeling of Tip clearances, and generates high quality mesh with nice boundary layers.
