Hi Andre, you may have all the answers I badly need; I am working on a radial inflow turbine and the meridional design is OK. I need an algorithm to build the 3D model. It seems you have done the development.
How can I use your application ?
Hi Liviu from Canada,
I've discovered a couple more open source projects since my last post. T-AXI and T-Blade3 (formerly 3DBGB).
http://gtsl.ase.uc.edu/T-AXI/BD%20Suite ... index.html
The authors of T-AXI include:
Professor Mark G. Turner, University of Cincinnati
Ali Merchant, Massachusets Institute of Technology
Dario Bruna, University of Genoa, Italy
Read the masters thesis on the T-Blade3 page. The literature review is very good. Make sure you've read Miller, BladeCAD An Interactive Geometric Design Tool for turbomachinery blades, 1996 (NASA Report) as well- it is important to understand why different coordinate systems are used in turbomachinery blade design.
I am working on a 1 stage radial compressor. For my workflow it appears I must use T-AXI as the first step to generate part of the input for T-Blade3 as Kiran Siddappaji writes in their masters thesis §2.1:
The input file also contains the xs and rs coordinates for all the nspn streamlines defined from an axisymmetric run like T-Axi [16, 17, 18, 19], or by smooth construction curves between the hub and the casing.
In LinuxTAXI/Documentation/T-AXI-API-ReadMe_New.txt it says:
To create input file for the 3D geometry generator, 3DBGB from T-Axi
>taxi_D -ga casename
This creates 3dbgbinput files for all bladerows.
>taxi_driver -ga casename
Read the example turbine input files ("t" in the .tti/.tts file extensions means turbine, "c" in the .tci/.tcs file extensions means compressor).
I'm still figuring out how to use the software from start to finish. I'll make a write up on my workflow once I've figured things out.
I hope this helps you in your work you badly need
