How do I find thrust and torque for a propeller in ANSYS Fluent ?
 
4 Attachment(s)
Hi All

I am doing a 4-blade marine propeller simulation in Ansys Fluent.
I import my geometry in Ansys Modeler.
Then i create an enclosure and subtract it from tool body propeller .
After that i complete meshing.
In solver setting i have some confusion. I setup enclosure as stationary frame and propeller is moving frame at rotation 400 rpm.
I also setup Velocity Inlet 5m/s.

After solving , to find thrust in CFD-Post, I write in table as =force_x()@propeller

Similarly, i continued it for different velocity like ( 3m/s , 6m/s).
My main problem is in there. When i increase velocity it also increases force of corresponding axis.

is it ok or having problem ?If its wrong then how do i find thrust ?
I am new in Ansys.
I am sorry for my bad english writing .

Please help me.

Thank You

Here are some photo of my works . I also attached in file section.
