arashm is on a distinguished road
hello everyone,

I'm designing a tidal turbine, I've done the design and now I'm analysing a 3D model of my blade with FLUENT. I need to obtain the torque and I'm little bit confused with the moment. are they the same ? cause when I get the moment the dimension is (N.m) which is the same dimension as torque so I derive that they should be the same. However, there is a huge difference between the torque that I calculated by hand and the one I get from FLUENT. I should say that I'm using the moving reference frame for the cell zone conditions and I set the blade as moving wall with a relative velocity of 0 rad/s to the adjacent cell zone, by doing this I simulate the rotational movement of my blade. so could you help me with this ?
