  • Lesson 17 appending and creating Turbomachine in Fluent

    Posted by Raghu Karthik on December 18, 2023 at 11:28 am

    In importing a turbomachine geometry first is read the msh file of impeller . next i read the volute mesh using append option . but every time i import the volute name is dropped by the software. in spaceclaim i named volute-outlet, volute-default. but the volute name is dropped by fluent solution. also I couldn’t create turbo interfaces as no available zones is listed (see pic) in create/Edit turbo interfaces .

    Doubt Continued…

    I tried changing the boundary type for faces impeller-to-volute 1,2 from ‘wall’ to interface then it showed up in the create turbomachines fields. That’s good. but its throwing some error when i hit the create button.

    I was able to do this. I did use a periodic BC while meshing. so i need not do pitching in create turbomachine fields.

      So did you use a sector model for implellor ? or you used a complete model

    Sector model

      when you use sector model…the areas of interface surfaces will be different. Will this be an issue ?

        rotational periodic faces should match. Since the geometry is provided to us for the assignment purpose they seem to be matching. I don’t know what happens if they don’t match though. It might through an error while meshing

          The interface on the impeller side will have 60 deg, and that on volute side is 360 deg. So how to match it in the simulation?
