Hello everyone,
I plan to investigate active flow control using steady blowing air on a toroidal propeller blade surface in ANSYS Fluent. A mesh motion is used to simulate propeller rotation. I followed the method in an AIAA conference paper for a stationary airfoil. But the velocity inlet boundary condition for the blowing sources became interface. Any insight would be appreciated. Thank you.
Dear Mingtai Chen,
I would like to advice for turbomachine simulation use CFX, because CFX solver is specially designed for this and usually reaches convergence faster than Fluent. If a wall becomes part of the interface in both solvers, there are possibility define non overlapping surfaces. I am not sure, but probably some limitations exist and better things exclude the wall from the interfaces. Maybe better to use MRF or sliding mesh that commonly used for turbomachinary tasks. I think possible organized air injection from a wall using DPM instead inlet boundary. Maybe there are other solutions.
Sincerely, Evgeniy

This paper used User Defined Function. I may try it as well. Thank you, Evgeniy.
To implement steady-state airflow on the fan blade surface in ANSYS Fluent, you need to create a high-quality mesh around the blade surface to accurately implement boundary conditions. You also need to define the inlet and outlet airflow conditions, which include the air inlet limits and the inlet air velocity. It's also important to specify the direction of the airflow (vertical or horizontal).
Set up the solver and run the simulation:
- Select a steady-state solver.
- Configure the flow field.
- Run the simulation until convergence occurs. For best results...
