Hi can somebody please explain to me what's the difference between optimization simulation of turbomachinery and NACA0012/OneraM6 cases?

For NACA0012/OneraM6 cases, we have some objective function like Drag which we are minimizing by changing the shape.

Isn't it similar for the case of turbines or compressors? There we just want to minimize/maximize the torque or pressure loss etc. by changing the shape? So, turbine/compressor's blade is also a aerodynamic wing in a sense?

What am I missing?

Sorry, I'm new to the field that's why asking such a question.

Aircraft wings operate in relatively independent airflow. Their performance is primarily influenced by their own design and the overall airspeed.

turbine blades operate in close proximity, affecting each other's airflow. This creates a phenomenon called "wake interference." As one blade rotates, the disturbed air (wake) it leaves behind can impact the performance of the following blade. This can lead to a decrease in overall efficiency if not properly considered during design.

in turbine/compressor/pumps, blade spacing and twist matters more, since it has relative effects on each other

EDIT: pumps means impeller blades

We had a turbo workshop at the last SU2 conference, you can watch it here:

Dear Bigfootedrockmidget,

I am interested in employing SU2 for shape optimization of turbine blades to enhance aerodynamic performance (e.g., efficiency, pressure ratio, etc.). I am aware that SU2 offers various adjoint solvers tailored for airfoil development, including both continuous and discrete adjoint formulations. I would like to inquire whether the discrete adjoint solver designed for airfoils can be extrapolated to shape optimization of turbine blades. Your response would be greatly appreciated.

Thank you.
