I am trying to calculate the axial torque of a film cooled blade.
The exit of the film cooling holes on the blade has a interface surface, so the entire blade surface, as I model the airfoil, cooled be selected.

However, the calculated value of the torque on the blade using the function "torque_z()@Blade" was lower then expected.

So I tried to find out how CFX calculates torque.
In case of the wall region, the torque can be calculated by the pressure and shear forces.
(areaInt_y(Pressure * X)@Blade - areaInt_x(Pressure * Y)@Blade) + (areaInt(Wall Shear Y * X)@Blade - areaInt(Wall Shear X * Y)@Blade)
In case of the film cooling hole exit, which is an imaginary wall in the fluid passage, could be a sum of pressure force and mass flow*velocity. But, this also shows difference in the values.
(areaInt_y(Pressure * X)@BLADE - areaInt_x(Pressure * Y)@BLADE) + (-massFlowInt(Velocity in Stn Frame v * X)@BLADE + massFlowInt(Velocity in Stn Frame u * Y)@BLADE)

So, I want to know how to calculate the film cooled blades torque right, and how the torque is calculated at planes in a fluid region.
