Parametric Volute - Loss of tangency at the outlet duct/scroll interface

Recommended Posts

Hi,


 


I’m currently working on the creation of a parametric volute with an overhung section. 


 


I have almost completed my model. However, after having exported my geometry to an external CAD in step format, I noticed that a loss of tangency occurs at the interface between the outlet duct and the scroll, in correspondence of the largest section.


For the creation of the outlet duct, I followed the tutorial available in CAESES: I used the fillet surface (with both tangent factors equal to 1 and edge sampling strategy with 50 nodes) to smoothly connect the outlet section with the scroll, after having defined two auxiliary surfaces.


 


Is there any correction I can apply to overcome this problem?


 


Thank you very much.


 


Cheers.


Simone
