Blade modeler

    • Mustafa Babagiray

      Hi everyone,

      I am trying to make a CFD simulation for the axial turbine. I created the blades in the blade modeler in DM. The turbine blades that we actually use in real have a constant thickness from the leading edge to the trailing edge and I wanted to do the same thing in design modeler but it gives me airfoil instead. As you can see in the picture, the tip of the blade has a sharp edge, I want it to be a flat surface. I mean when you look at the shroud the top surface of the blade should be rectangular. Do you have any suggestions about it?

      As you see the blue line represents the current tip of the blade and I am trying to make it as red line. The full illustration of the blades can be shown below.

      Thanks in advance

      Hello Mustafa,

      I would recommend you to look at the  blade LE and TE definitions, you can change them to other options to get the shape you want. Note there are only 3 options: rounded, square and cutoff in blade gen. So you can choose the square option . Also there is a blade blend option to add thickness at desired cross section. Kindly refer this link to perform it.

      10.2.3. Blade Feature (ansys.com)- Refer Blades made using Camberline/Thickness Sub-features

      This should solve your problem.
