Calculating torque from moment results in CFD analysis

Click For Summary
SUMMARY

This discussion focuses on calculating torque from moment results in a Computational Fluid Dynamics (CFD) analysis of a turbine. The negative values obtained in the analysis indicate the direction of the torque, which can be either clockwise (CW) or counterclockwise (ACW). To determine the available torque force for turning a generator, the negative moments must be summed. Understanding the sign of the torque is essential, but it may not significantly impact the generator's operation.

PREREQUISITES
  • Understanding of torque and moment concepts in physics
  • Familiarity with Computational Fluid Dynamics (CFD) analysis
  • Basic knowledge of turbine mechanics and operation
  • Ability to interpret engineering diagrams and results
NEXT STEPS
  • Research the relationship between moment and torque in physics
  • Explore how to perform torque calculations in CFD software
  • Learn about turbine design and its impact on generator efficiency
  • Investigate the significance of torque direction in mechanical systems
USEFUL FOR

Mechanical engineers, CFD analysts, turbine designers, and anyone involved in optimizing generator performance through torque calculations.

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.
