Dear developers and users:

I want to use su2 to analysis the flow around a quad-rotor uav, which have 4 rotating blades.

I am wondering if it is possible to define multi-rotating centers in config file, do i need to have multi-zones in the mesh file, or any suggestions for this kind of analysis by su2.



Thanks in advance

Jin

Hi Jin,

At the moment, it is not possible to define multiple rotating reference frames. You might want to read some more information about the current capabilities in the code related to this topic in the thread here: 3D external periodic multi-zone flow with RANS-based Turbulence model.

I should also mention that we are starting to implement an actuator disk boundary condition in the code, and this would enable the type of simulations that you mention (modeling each of the 4 blades with a disk). Stay tuned for more info on that topic in future releases.

Hope this helps,
T
