Paper by Tandis et al. "Analysis of Coupling Strategies for Conjugate Heat Transfer Problems"

This week, we're heating things up with a deep dive into Conjugate Heat Transfer (CHT) simulations! We are excited to feature a manuscript in the OpenFOAM Journal that analyzes and improves upon crucial CHT solving strategies.

Analysis of Coupling Strategies for Conjugate Heat Transfer Problems
by Emad Tandis, Philip Cardiff, and Ali Ashrafizadeh.

This work addresses the persistent challenges of accuracy, stability, and computational cost in CHT simulations within the OpenFOAM® framework. The authors present:

• A detailed analysis and commentary on existing OpenFOAM CHT solvers.
• Two modified CHT approaches: a new partitioned algorithm with improved efficiency, and an extension of the monolithic solver for multi-region problems.
• A thorough performance assessment showing the superiority of the proposed monolithic approach for complex cases and the significant computational speed-up of the new partitioned solver.

This research offers valuable insights for anyone looking to optimize their thermal-fluid simulations.
