Overview

This research employs extended dynamic mode decomposition to achieve fast and accurate thermal-fluid simulations in transformers, enhancing digital twin applications.

Key Points

  • The proposed method reduces computation time from hours to minutes while maintaining high accuracy in thermal-fluid simulations.
  • Errors in thermal and flow field calculations were below 3.06% and 3.01%, respectively, demonstrating reliability.
  • Using extended dynamic mode decomposition enhances computational efficiency, achieving speed-ups of 97-fold for thermal fields and 83-fold for flow fields.
  • This approach supports the real-time performance demands of digital twin technology in power equipment simulations.
