I'm working on a project with flowmeters.
The question is, what is the best design for the worm in order to get te best efficiency in a flow meter.
I've added a picture to show the model.
I know it is possible to determine equilibrium rotation of a propeller in ambient flow.
Set a goal for the torque around the axis for all the faces of the propeller and see if it's driving or resisting.
I did some testing to see the difference between selecting ALL faces or just ONE as a " sensor " face to determine the "+" or "-" vallue of the torque.
The vallues are quit different and therefore I'm doubting my analysis.
- Is it neccesary to select ALL the faces of the rotor?
- Is there an alternative for placing a sensor goal to measure the equilibrium rotation?
Thanks in advance.
