2D linear cascad in TurboGrid (Meshing)
Hi!
I have a problem that I hope anyone can help me with. The problem is that I would like to "mimic" a a 2D Blade-to-Blade calculation in CFX by using TurboGrid. My idea is to mesh a linear cascade section and set the end wall (hub & tip) boundary to symmetry. (Ideally can the cascade span be wery short (2 cells?)). The problem is that when using turbogrid the hub and shroud will be swept and therefore not suited for a symmetry bundary. So is there any way to have straight endwalls in TurboGrid that can have symmetry boundary condition? Regards//Adde |
I am wondering this too. Any luck in finding if this is possible?

make the inlet and outlet as hub and casing. this way you can trick turbogrid and get the required mesh in it.

Hi Far,
Thanks for your reply - I'm not exactly sure how you mean - the only thing I can think of in terms of tricking TG to do it is to make a blade that is just 2D profiles stacked in 3D and then set the number of blades in the full annulus to something ridiculously high and scale up the the hub radius in order for the hub and shroud to have no curvature. Im not too sure about the robustness of this method though. Is that what you mean? Thanks! |
