Calculating torque from moment results in CFD analysis

Click For Summary
The discussion focuses on calculating torque from moment results in a CFD analysis of a turbine model. Negative moment results need to be combined to determine the torque force available for turning a generator. The sign of the moment indicates the direction of torque, either clockwise (CW) or counterclockwise (ACW), but may not significantly impact generator operation. Understanding these negative results is essential for accurate torque interpretation. The conversation emphasizes the relationship between moments and torque in engineering applications.

Hi there, attached were the results: https://prnt.sc/v3yg1f
Both are negative and need to be added together to get the torque force. Calculations are from a model of specified radius and input air speed, its a turbine. Just need help in understanding what the negative results mean and how they are interpreted, and therefore what torque force is available to turn a generator. Thanks

Welcome to PF.

An engineering “moment” about an axis, is a “torque” in physics.
The sign specifies the direction of the torque. CW or ACW.
The sign is probably not relevant when turning a generator.
