Computational Fluid Dynamics--Machine Learning Prediction of Machinery Coupling Windage Heating and Power Loss

Couplings connect the spinning shafts of driving and driven machines in the industry. A coupling guard encloses the coupling to protect personnel from the high-speed rotating coupling. The American Petroleum Institute API publishes standards that restrict the overheating of the coupling guards due to windage caused by the spinning shaft. Based on the most recent version of API 671, the peak temperature for the coupling guard should not exceed 60 C. This paper proposes a machine learning (ML) model and an empirical formula to predict the maximum guard temperature and power loss.
