bladegen data import issues
 

Hi all.. i have a single stage axial turbine to perform a CFD analysis.. i tried to import the IGES model to bladegen , but it seem it s not getting read. I always receive a error message saying it can't read the data. Which version of IGES is required for the same ? is that an issue? please help me...

In my opinion you have to read the IGES file with the DesignModeler. After that you have to construct some lines or planes (I have seen it only once during a training) to "extract" one channel and the boundaries of that channel (this is a description of the boundaries by many points, which can be used to create two lines).

For that procedure you need BladeEditor (take a look at wb_bm.pdf in the documention for the TurboSystem). BladeEditor is a plugin for DesignModeler to follow the steps I have described here. You are than able to mesh the turbine with TurboGrid. I am not sure, if you can load it into bladegen then, too. Take a look at the different components of the turbosystem and when they should be used.

thanks max..... will try that nw itself, by the way is there an tutorials available for blade gen....? i searched in the net, bu was not useful..please give som elinks, if you hav any...

thanks in advance....

There is BladeGen.hlp help file in the following directory C:\Program Files\ANSYS Inc\v121\aisol\BladeModeler\BladeGen . I have not found any tutorials yet..and do not think there exists...

You could also try to put your model to TurboGrid like Max said:
1. Firstly configure your BladeModeler license so that the BladeEditor plugin for DesignModeler is activated (look in this pdf wb_bm.pdf how to perform this). You will have then a new toolbar with new features in Desin Modeler.
2. You just need to attach/import the Cad model (or Iges file) to Design Modeler.
3. Make a flowpath feature with meridonal sketches of the hub,shroud,inlet,outlet.
4. Use ExportPoints feature to transfer the blade to Turbogrid.

Please try it and report if you were successful! I am also trying to do this, but I am stuck at ExportPoints, there is always an error. If somebody made it through from CAD to Turbogrid please tell me!!Thanks!

hi la7low.............

thanks for the help. let me try it....

but i can not use in parameter as parameter input >>>>for using optmization method>>>any one help

not used as geometical parameter

How to calculate the wrap angle and flow angles
 

Can any one guide me as to how calculate the Warp angle and flow angle from the airfoil shape, I have airfoil data of rotor blade but hoe to input the blade angles from it in ti blade gen.

Thanks
