Bladegen Data import wizard (Creation the existing turbine blades in bladegen)

    • Mustafa Babagiray

      Hey everyone,

      I am working on turbine blade optimization for a specific flow rate. I have the CAD design of the turbine runner attached below(1), but I wanted to convert it into the bladegen by using the data import wizard. I attached the steps that I have taken in the data import wizard, I selected hub and shroud curves and the meridional profile is created. (No problem until here). However, as you see in picture 7, I want to have the hub surface as a flat surface as depicted in the picture's red lines without any changes in the blade shape. I mean everything is correct except the flow path starting point. It should be perpendicular to the blades. Do you have any suggestions on how to do it?

      Hello Mustafa,

      I recommend you  to set the zr locations for the hub & shroud curves at outlet and TE to be the same values. You can double click on the points and set the values. This should create a flow path perpendicular to the blades . I am attaching the user guide on link on flow path feature for further details.

      10.2.1. Flow Path Contour Creation (ansys.com)

      10.2.2. FlowPath Feature (ansys.com)

      I hope this helps you solve the problem.
